In an article, published by the Journal of Mountain Hunting, 

https://journalofmountainhunt ing.com...el-broadheads/

Dr. Ed Ashby makes an argument, based on his studies, that single-bevel broadheads of the proper design are more effective at splitting bone than double- bevel heads. He acknowledges that double-bevel broadheads will go through bones; but he concludes that they will not exert the kind of twisting rotational force needed to split bones apart (rather than simply slicing through them), as single-bevel heads will. He argues that where bones are struck, this difference is important for penetration because bones that are split apart by that twisting rotational force will allow an arrow shaft to enter and penetrate with less drag, and that shaft drag is a big factor impeding penetration. He contends that the rotational twisting force delivered by the single-bevel broadhead is at its strongest when the broadhead encounters an unyielding material such as bone. 

This argument of Dr. Ashby’s is of particular significance for hog hunters, because (1) hogs seem to be heavy-boned for their size, and (2) mature boars have a gristle shield that might be hit by accident or on purpose, and end up having to be penetrated. This question is for the hog hunters: Have you hit a gristle shield with a single-bevel broadhead? Have you hit one with a double- bevel broadhead? Does your own experience suggest that hog hunters would be better off using a single-bevel broadhead?

Well if single bevels were the only thing that worked, it would be a different story....but they are not. And I think hog hunters should decide for themselves. There's been a lot more killed with double bevels over the eons than any other broadheads. We all know what Fred Ashby suggests and I'm sure they work very well, but not to the omission of anything else.

George summed it up nicely.

One of the biggest boars I've taken with a bow fell to an "old fashioned" Magnus 2-blade double bevel head, and it was ONLY 100 grains. LOL

Shooting 9 gpp and just 52# the arrow penetrated his very thick shield, then his heart, then stopped in his sternum (it was a steep downward angled shot) where it protruded out the bottom after having penetrated the sternum.

Not sure how much more penetration a person needs actually.

I went to a single bevel last year, and was impressed once I saw how they worked out of my long bow,,,,, so that is what I use now on my trad gear...... proof was in the pudding

I have killed hogs with many different types of broadheads. IMHO a 160 grain rothaar snuffer or extremely wide 2 blade such as a Treeshark and or interceptor will greatly increase recovery %. RC on this site lives near fort Stewart GA and kills a ton of hogs with light bows, he prefers treesharks. I was assigned there in the late 90s and killed a ton of hogs, mostly with a 77# hybrid and big snuffers or simmons interceptors. I have killed them with grizzly kodiaks, ribteks, magnus, ace standards, eclipse, but blood trails are slim/scant. My wife used tuffheads on her 43# longbow on a texas hog hunt a couple years ago, and she shot 3 pigs, and not single drop of blood on the ground with any of them, to include complete pass thoughs. I am sure the shots were fatal and clean, but no blood trail. Last year a friend killed a big hog with a zwickey eskimo 2 blade, complete pass though, no blood trail. The next day I stumbled across the dead pig 200 yards from where he shot it. I have recommended 3 blades for hogs for all who will listen. Several went VPAs and were happy with pork in the freezer on follow on hunts.

Michael -

I see your point.... but then I can foresee more penetration issues as total frontal cutting edge increases. Not that I’d sweat it much at #77, but it’s unlikely that I’m getting a full #47 out of the #50@28” on my Howatt Viper.

Makes me wonder about the rotation, though - I've noticed that a Magnus 2- blades spiral their way through my target; just not sure what kind of bone hit is the max that you can expect to get through without killing that rotation? Also curious what happens to the rpms with a single bevel; increase? decrease? Does it matter what angle you put on when you sharpened it? And does it matter if the two edges on a given blade don’t quite match? What happens when the single- bevel edge is trying to spin the arrow (in the air) at a different rate of twist? Obviously, the fletchings will win that battle, but THINK OF THE TURBULENCE!!!

Or you could shoot what you like.

I have every intention of switching to single-bevel... just as soon as I’m convinced that I can get them sharper than doubles.

I have had the same problem on hogs. I use two blade. Had good blood trails to start then just dry up.

I've taken my share of hogs, using the Howard Hill broadhead and a head of my manufacture based on the Hill with a steel ferrule all of them with double grind and only had trouble with one of them, that I searched and chased for close to 8 hours finally got him and the problem wasn't the broadhead other than it wasn't in the right place.

From: David McLendon
Date: 06-Nov-17




Yes,Yes and No. I have had my best success with a 160 grain Snuffer and that is what I use on just about everything. You need to ake sure that you have enough bow to drive the big Snuffer, especially on big hogs. My second choice and it may be the best choice but I have only killed two hogs with it so not enough to tell is the Simmons Tree Shark. Penetration is excellent on the Simmons and you can google pictures to see what kind of damage it does. Since Simmons has withdrawn from the glue on market I plan to go to the Centaur Big Game head which is a heavier built head. I've used Grizzly and they do penetrate well but produce a narrow wound channel, nothing like the damage of a Snuffer or Tree Shark, both of which produce short blood trails like they were poured out of a paint bucket. :)

I don't agree with George that we should one at a time decide what works for us. On that basis we wouldn't have bows or arrows even, if we gave up the lessons of history. One person is hardly enough to decide a mater like this, and what about all the experiments gone wrong along the way to full understanding. I'm happy to make up my own mind without having to run down the best broadhead study we have ever seen.

Of course other options work well, but single bevels have a significant sharpness advantage, particularly on 3 blade heads, and bone splitting is an extra on top. Grisle, not sure what the advantage is there. You don't split it, a sharper head should penetrate it better.

All that said, for deer and black bear, I figure double edge is fine, even if not optimal. I bought 150 ribtek heads for a nice low price, and feel the advantage of being able to practice extensively with broadheads is sufficient reason to forget about buying heads in the post Ashby period. The main effect Ashby 2 has had on me is to double the price of the heads I used to buy. Along with a few of the makers passing on their businesses to new hands who understandably needed to raise their prices.

I've killed a bunch of hogs, all with Bear Razorheads. Never lost one and blood trail on every one. Well except for the one that dropped in his tracks.

From: dean

Howard Hill developed his broadhead and sharpening style testing on hogs. In his writings, he talks of the subtle concave showed improvements, as well as the serration sharpening method adding to penetration. The end all of knowledge, probably not, but a sound objective approach. I gave one of my single bevel Hills to a local fellow that was going hog hunting. I sharpened it so it would shave hair and then did the Mussato serration from the beveled side with an adaptation considering the single bevel. I told him to keep it in the sheath until use, don't miss and don't lose it, he was not getting another. He shot through a hog, lost the arrow, but the shield did not stop the arrow and it bled out fast. His report proved that they work, but that is all. Another local, shot one with a file sharpened Eskimo on a 1918 with my fletching and got nearly the same results. Skinny shaft with good weight and a fairly steep helical to get the arrow weight straight behind the head, maybe was more important in that case. Lots of variables, which can make a difference in each individual situation.

Before the internet, almost every person i have known in archery learned what worked for killing different animals by hunting and killing them. I haven't found an animal yet that an Ace express won't put down quick, and haven't found any head that i would switch to from them. I shot probably 50 different heads when i was in the industry and firms would send me heads to try. Some worked as well, but none killed any deader or went further in the dirt after a pass through. Company's make sales by trying to reinvent stuff on a constant basis. This is the second time around for single bevels in my 60+ years of hunting with a bow. I'm still not impressed.

I've killed them with Grizzly single-bevel heads, Ribteks, Zwickey Deltas, Simmons Interceptors, Ace Super Express and VPA three blades. I've also lost a couple with a VPA and a Simmons. I've also seen other people kill and/or lose them with a variety of heads. Other than mechanicals (just say no), I can't tell any difference due to the head -- it seems to be all about placement. Low and forward puts them down quickly with a lot of blood; anything more than 1/3 of the way up is likely to be problematic.

From: David McLendon

Lots of single bevels out there now, the only one I have tried over the past 10-12 years is the Grizzly in 160 & 190 grains, and I gave all 24 of those away about two months ago. I will stick with double bevel 2 &3 blade heads. I have a stash of Snuffers and Magnus 160's. It ain't broke...

Will a single bevel give a some edge on bone penetration? Likely (some), but it isn't a magic wand to compensate for a bad shot.

Years ago I killed a few pigs (deer too) with some single bevel Grizzly heads. They did great, but no better than any of my other favored broadheads, and I eventually went back to my old standard double bevels.

I have killed quite a number of hogs, and encountered a lot of bone to be penetrated. They all did the job.

I've also used some broadheads, that I will "NEVER" use again due to their weak design. That leads me to the following:

To me, there are only three factors to consider when selecting a broadhead, none of the three are any less important, than the other two.

(1) That they have good structural integrity.

(2) That they can be adequately sharpened.

(3) That they fly well.

I'm not gonna poo poo on single bevel. I'm using them right now, but the "Main Reason" for that is the ones I am using are almost indestructible. I don't have to worry about them bending, or breaking when they encounter bone.

A quality tool steel machined single bevel head is thick & stout. I like that. Of course they sharpen, and shoot great too, or I wouldn't use them.

Do ya think the broadhead in this picture went through some heavy bone? If so you would be correct. This pig went down right where he stood, and never even so much as quivered. That's a 3 blade double bevel on the end of that arrow.

"Before the internet, almost every person i have known in archery learned what worked for killing different animals by hunting and killing them."

Well apparently they didn't come to the same conclusion, even in circumstances that are remarkably similar, or we would be down to one head. So that kind proves my point that we need not 50 thousand tiny studies, but some overall study, and it would help if the guy doing it, was doing it as a study not as a series of hunts that were never intended to be conducted along scientific lines.

I am not saying that single bevels are best. I have zero idea. And I said I made up my own mind, but it was based on management principles, not scientifically. I don't know what broadhead is best, I do know how to manage my personal situation.

"Company's make sales by trying to reinvent stuff on a constant basis. This is the second time around for single bevels in my 60+ years of hunting with a bow. I'm still not impressed."

Ashby isn't selling broadheads for profit as far as we know. He originally came out with the same result relative to Grizz when Mrs. Elburg was making them one at a time. I doubt there was a huge slush fund to buy off Doctors hunting in Africa.

The first study was not based on the ideas he later observed about splitting. The Grizz won as a regular head.

If I had your record and experience, I would make up my mind for myself also. But it still wasn't done, from what I understand, on a scientific basis.

"I'm going to disagree with "Bowlim" on one point! I personally can get a double bevel sharper than a single bevel. So don't judge everyone's ability by your or someone else's.

Bob"

Those would be variables, that one would eliminate in a scientific study. Based on threads here, Grizz was a huge learning experience for people, and on that basis alone, probably a failure to lift off. And also part of the reason a lot of people went back to 2 bevel.

The reason single bevels are "sharper" is only geometry. when You do an identical chisel grind the bevel is twice as acute. So your 45 deg 2 bevel becomes a 22.5 chisel grind. Which is actually pretty close to the 25 degrees a chisel is ground to, and those take a lot of abuse. That effect massively increases cutting power, and while it isn't sharpness in the sense of a more refined edge, it is going to play like is is. So long as the edge holds up.

Now you can double grind to 22.5, or whatever if you wanted to, just doesn't tend to be how it is done.

As I never tire to point out, The Grizz was single bevel due to construction, not as a design objective. It just ended up that way, and the advantages flowed from that as they were discovered.

From: Phil Magistro
Date: 07-Nov-17




Bowlim, from what I recall, Ashby's work was done over a 30 year span and was published in the mid 90's. It was noticed but it was more heavily promoted in more recent times by at least one company that benefited from selling products. I don't know if he ever made any money by loaning his name to at least one company but good for him if he did.

It would be a very difficult task, if not impossible, to complete a scientific study on broadhead performance due to the inability to recreate all the variables so anecdotal evidence is all we have. I have no doubt that some designs are better performers than others but I know people have killed critters with what I consider an inferior broadhead.

Two simple truths, there isn't a broached made that is more deadly than any of the others. Secondly, if you had three guys at a table talking about what the best broadhead is, the only thing they would agree on is that the other guy is wrong.

I've shot hogs with single bevel, double bevel, and woodsmans. Any good head will work fine on smaller to medium pigs. Blood trails can be great, or poor with any head. On bigger boars the shield is no joke. If your arrow isn't built for the job the shield will stop it regardless of the head used. Arrow weight becomes more important than the number of blades or the grind of the edge.

From: Ollie Professional Bowhunters Society - Qualified Member Compton's Traditional Bowhunters
Date: 07-Nov-17




Any sharp broadhead is capable of killing a pig if hit in the right spot. Small hogs are easy to penetrate and kill. On an older boar the shield can be quite thick and will hamper penetration. Hogs are very difficult to kill with marginal hits. In my opinion and experience, single bevel heads will penetrate better than double bevel and three blade heads. I've killed hogs with all three mentioned heads. I go with the head that I think gives me the best chance, and that is a single bevel head.

From: SuperK
Date: 07-Nov-17




Well, I never have shot a hog with one but I have used them off and on for several years on deer. I was even using them before I knew about matching the bevel with the feather, etc. I would like to share what I have observed. When I started shooting wood arrows, I really liked them because I found that if the arrow would fly well with a field point, it would fly well with the Grizzly broadhead. I didn't know a whole lot about tuning wood back then. Any long, narrow broadhead is going to be more forgiving than a short, wide one. I experienced good,steady bloodtrails with good hits. I can't say they were any "better" than I got with Eskimos, Ace or other 2 blade broadheads. The "splashiest" bloodtrails I have got were with Woodsman broadheads. I haven't had many (one or two maybe) "L" shaped entrance or exit wounds due to the single bevel effect. I haven't seen any "bone splits" due to the rotation of the single bevel. I don't shoot 650 grain arrows either out of my 45 pound bows either. I have seen the edge "roll" on a buck that I hit in the spine. I have learned how to get them sharp. The newer ones are a lot easier than the older ones. I don't like how they fit in one of my quivers. It leaves a lot of blade uncovered. I don't like the "tanto" point. After watching a video where a man pushes several different broadheads through a piece of thick leather, I tried it myself. A regular Eskimo took a lot less pressure than the Grizzly. Grizzlys are offered in more weights than Zwickeys. Ace Standards come in more weights than either. So, my conclusion? They are good broadheads. So are Zwickey, Ace Standard and a bunch of others. For me, I don't see that big of an advantage. Get ya' some and try them out for yourself.

I've split bone with double bevels.

Pat has a test on Bowsite where he split the bone on a cape buff with double bevels.

Double bevel knives have been around for a very long time and the functional reasons for the double bevel make aheck of a lot of sense.

Its kind of funny to me really.......So one guy comes around and says, "Single Bevel" and many folks follow in lockstep hook, line and sinker.

I too agree with George, I have killed more then a half dozen hogs with a 46 pound @ my draw recurve. And a Magnus 2 blade stinger. Two of those were good size boars. One with a very thick shield. I watched the hog go down in like 40 yards. That surprised me, The arrow penetrated the shield and the hogs heart. But I got no exit wound. It is all about arrow placement and sharp broadheads. Doesn't matter if they are single or double bevel. I will say out of 7 hogs shot with that same set up I watched 3 go down.

We went to a hunting camp in Texas every year for many years . When we first got there most of the hunters were using the narrow single bevel heads, they were told that it was the only head that would penetrate good enough for hogs and javelinas. Lots of animals got shot on the first morning, I think it was about 8 ,only one was found and he found that by accident while heading back to the truck. I used three blade and found both the animals I shot that year . Since then I've only shot about 20 hogs I have shot all with the WW its worked good, I can only remember losing one hog. This year I will use my old Razorheads with the bleeder. As far as splitting bone with the twisting action, I,ve seen the pictures of that, it looks like the arrow may have split the bone but they stopped right there didn't penetrate in to the lungs. I would rather have a bounce out than an animal running around with a broken shoulder bone. Best thing is to not shoot them in the big bones .

Grizzly (now made ny Zipper Bows) has recently come out with a new model called the "Bruin" that looks interesting. It might meet Rick Barbee's criteria. It is like the Grizzly two-blade heads except that it is double beveled rather than single beveled, is made of three laminated layers rather than two, and is thicker. The 150 grain weight is .06" thick, the 175 grain version is .065", and the 200 grain version is .07". The regular single bevel Grizzly is .05" in thickness.

tradmt: Rick Barbee put an interesting video on youtube comparing penetration into a test medium of a 3-blade broadhead (it was the 175 grain VPA 3 blade) against a two-blade (double bevel) broadhead of somilar weight. The 3 blade broadhead won handily. The test medium was a box of tamped-down sand, surrounded by a fabric. Probably the 3-blade out penetrated the two blade because a 3 blade head will create a larger channel through the test medium or game animal, and then there was less shaft drag to impede penetration.

Steven (oldnewby),

I've done all kinds of broadhead penetration tests, experiments, and challenges, AND tried very hard to get folks to join in on them in an effort to create an across the board data base of results from varying equipment for folks to draw some of their conclusions from.

I was sure there would be folks from certain factions (proponents of High FOC, Single bevel broadheads, Heavy draw wiehgt, Heavy arrow weight, etc, etc) who would jump all over the opportunity to strut their stuff in a heads up comparison against other equipment,

BUT

to date - no one has joined in on any of them. I finally gave up trying.

Makes a feller go - "HMMMMM, I wonder why no one wants to show their stuff?"

Wayne, my entire goal for such an adventure was simply to create a real world data base to compare varying equipment for arrow/broadhead penetration. No one wanted to join in.

I was confused by, and quite disappointed at the lack of interest.

I still to this day think such a gathering of information all in one place would be highly beneficial for folks.

I would be quite interested in the results. I do remember you worked pretty hard to get some participation and we all stayed on the porch.

Count me in if you do it again, Rick. Hope others will commit as well.

"Bowlim, from what I recall, Ashby's work was done over a 30 year span and was published in the mid 90's."

Yeah, I got the first study from monographs Bowhunter's Discount Warehouse was selling. It had little impact, and the price of Grizz heads remained low for a long time thereafter, as was intended.

"It was noticed but it was more heavily promoted in more recent times by at least one company that benefited from selling products."

As far as I know he published a second study that updated the ideas and said that for instance the oversize head, now the Kodiak (?) head, the sorta Atlat sized one was the way to go. Added info on single bevels splitting bone. I really don't want to have to re-read the first study again, but I don't remember the single bevel being a big deal, Grizz were stronger and penetrated better, being basically Hill style. And the sharper thing. He also added the info on how to make arrows that penetrated better, 650 grain claim, and so on.

After that study hit, it got a lot of play and the blizzard of single blades appeared. There is one company that has his studies on their site, and lists him, but explicitly says he has said he wants nothing to do with them financially.

" I don't know if he ever made any money by loaning his name to at least one company but good for him if he did."

Well good for him but people would say what has already been irresponsibly said in this thread, and if you have real money, which some doctors do, stipends from broadhead companies are not work the liability.

"It would be a very difficult task, if not impossible, to complete a scientific study on broadhead performance due to the inability to recreate all the variables so anecdotal evidence is all we have."

Does that go for every claim that is made about "scientific wildlife management" that pro hunting groups have made, or just when it relates to tests undertaken to deal with broadheads? In reality we make many studies about stuff like weather, where there are many more variables than we can yet comprehend. They can still be considered scientific studies if various criteria are met. Joe Blow Broadhead's experiences are not on the same level as someone with scientific training, a medical background, world wide bowhunting experience, who has set out to conduct a serious study, that will itself be subject to review by those it is conducted for, who have their own life long experience in hunting and the outdoors.

I don't get why so many react as though the existence of a reasonably conducted study impacts their right to do as they please. Smoking may cause lung cancer, but a lot of people keep right on with their preexisting behaviors. As is their right. Doesn't qualify them as research scientists, however.

Rick Barbee is right. It would be of enormous value to all of us who hunt to have some kind of coordinated testing of arrows and broadheads. The existence of boards such as Leatherwall make it easy to coordinate what we are testing and how. Even if you don't want to put a video on youtube, as Rick has done, you could post your results along with a photo or two. There is too much of people repeating what they read on the internet, without testing it themselves. Rick tested the often-repeated "truth" that a two-blade broadhead will penetrate deeper than a 3 blade head shot from the same bow, and found out, at least with his setup and testing materials, that it was not correct. Think what we could learn if we all helped a little and coordinated what we are doing. There should be a new separate thread on this, shouldn't there? If I start one, Rick, may I invoke your name quote you?

I think all states should adopt a law where only single bevel broadheads can be used.

The old penetration challenge should be disregarded. The links, and links to the pictures in it no longer exist.

I have it all saved. I'm thinking about, and probably will kick off a new one sometime soon.

I have hunted pigs one time. Killed a pig of approx 100lbs. 2117 AO, in one side and out the other side with the crappiest broadhead ever made. 3 blade Satellite with blades so thin you could bend them with a finger. He only went 50 yds, and I could see blood squirting out both sides as he ran away.

Well, I thought I would bring this thread back up because I wanted to share some recent experiences with Grizzly broadheads on 3 deer I took this year. The first was a nice sized doe. Good rib cage hit. Slightly angled forward. 50 yard dash and crash. Good, steady blood trail. Nearly a complete pass thru. The second and third were spine hits. (not trying to hit there but it happened) The first was a spike buck and the last was a big doe. Both went down on the spot. Nothing unusual about that. What was unusual was the Grizzly broadhead completely penetrated the backbone and a rib was all that kept it from comming out on the other side (the buck). On the big doe, the broadhead was wedged so tight in the backbone, I couldn't move it at all. I nearly didn't get it out. I noticed that 2 ribs were cut in half next to the back bone. I have been bowhunting since 1973 (with all different kinds of bows and broadheads) and I have never experienced this kind of penetration in heavy bone. This was with a 45 lb. recurve with fast flight string, drawn 27 inches. Arrows were Douglas Fir and weighed approx. 525 grains. This time the broadhead and feathers were matching. (left wing feathers, left bevel Grizzly) Did I experience "the single bevel advantage"? Has anyone else "seen" this with low poundage bows and sub-650 grain arrows?

Ace Standard == Deer 1 #50- selfbow, B50 string, cedar arrow, blew thru the deer like it wasn't even there... down in 20 yards. Deer 2 #47 home made Hill bow, B50 string, same cedar arrows 125 Grain Ace Standard, steep angle shot, right thru thru the heart, stopped on off leg, ran 60 yards and dropped. Both Ace heads were filed a rough sharp with cross cut files on a V Block.

Friend is disappointed with Grizzlys, he is a seasoned hunter, going to tree sharks

If they want to. Lots of hogs killed before single bevels became popular. I lost count long ago and haven't sprung for any new single bevels yet,only because I have plenty of heads. No doubt they perform very well though.>>>----> Ken

Grizzlys stink. Please pm me and I'll tell you where you can send them for safe disposal.

"Grizzlys stink. Please pm me and I'll tell you where you can send them for safe disposal."

I have been trying to trade a dozen Grayling Bear razorheds for any right wing Grizzlies. Seems like there has been no one interested in a trade so far. I will even sharpen the Bears' and take a dull grizzly in return! TLM
