single bevel vs double bevel

[Junkers88]

Does it really matter with traditional bows? I've read that the decision on 1 or 2 bevels on a broad head is purely personal. Some say that a 2 bevel BH is a stabbing wound while a 1 bevel BH is a spiral wound so the 1 bevel does more damage.

All things being equal, to include the dingbat holding the bow, is one BH better with traditional bows than the other?

Yes, it matters with traditional bows. Nothing about traditional bows makes the point moot. In fact I think the whole discussion of which was better was started before there were compounds (could be wrong, but I wasn't old enough to know when that transition happened.)

To what degree it matters in general is another topic all together.

I believe Ed Ashby has found that a single bevel broadhead design can have a greater ability to break bone if contacted due to the wedge shape of the edge. Many other factors come into play, such as optimum shape (3 to 1), true flight, overall arrow weight, percentage of arrow weight front of center (FOC), as far as penetration is concerned.

None of the critters I have killed with my double bevel broadheads would have been any deader with single bevel. I think putting that broadhead in the right place is the most important thing of all!

Just be sure the bevel and helical of your feathers are on the same page. And yes, shot placement is #1...and I'll go ahead and DUH that for now cuz I'm still workin' on perfect every time. All broadheads are pretty awesome when the shot is perfect. Nice to have good penetration (and hopefully not a wounded critter) for those not so perfect shots too.

I think Bisch pretty much nailed it. I think there may be some slight advantage with single bevel on less than perfect hits. I've killed lots of critters with double bevel broadheads. I decided to try some single bevel broadheads and the last 3 pigs I killed were with single bevel. I didn't notice that they were any more dead than the ones I killed with double bevel broadheads. Remember that you have to match up the bevel with the feather, that is, left bevel with left wing feathers.

A second on Dr. Ed Ashby- broad head lethality study, more about broadheads than you ever wanted to know. Single bevel fan here, there are no degrees of dead, any broadhead in the sweet spot does the trick, you ever get to see a single bevel go through leg bone to get to the sweet spot, you can't help but be impressed, you may be converted but you will be impressed.

I like Grizzly broadheads because they are easy for me to get really sharp.

Thanks folks! Getting reliable information like this is the exact reason why I became a supporting member about an hour ago. Well worth the small yearly investment.

in some shot situations/locations the single bevel provides a theoretical penetration advantage but Ashby's studies involve a lot more arrow variables than just bevel configuration. some of the information is just not pertinent to me because I don't (can't) shoot the draw weights he describes to fling those extremely heavy arrows

any shot I've taken that resulted in poor penetration was due to poor shot location (operator error) and would not have been improved with a single bevel broadhead

with single bevel you will move through the woods with less effort because you will be carrying less money in your pocket

I have read Ashby's reports and found them very interesting and have no reason to doubt any of the information there. Too bad we don't have more good research like this.

That being said, I shoot the more affordable two bevel heads, Zwickey and Magnus. I have a harder time getting some of the single one's sharp.

This is really advanced bowhunting. Like my many friends above said, in Texas, if you put a sharp head in the right spot with good arrow flight...nothing else matters.

With a lansky diamond kit you can get grizzlies very sharp. I happened in to three dozen of the old ones and have to use a file to set my angle. Any good broadhead will do the job. The most important part is to be confident in them and do your part. If you are second guessing your equipment it can lead to some mind games.
