Iron will chipping

[Mighty Mouse]

The problem with broadheads chipping is not because of it being single bevel. It’s due to steel quality. TuffHeads are scary sharp 30* single bevels that I have killed a bunch of animals with. Never chipped ever. Its the steel not the bevel.

Just had my 1336 grainer pass thru into the dirt hillside. Just the latest example of never chipping.

I agree that steel quality is a very important factor in edge retention. But I would still contend that—for any given grade of steel—a double bevel head will retain its edge better than a single bevel. Bill at Iron Will discusses single bevels here (skip to 2:50): https://www.rokslide.com/deep-in-arrow-builds-with-bill-vanderheyden/

"The negative with having that single bevel is that you get all this pressure on one side of the blade and they're more likely to want to roll the edge or break out little pieces of that edge and cause some, kind of, edge chatter."​

Update. I have been frustrated with chipping on my single bevel Iron Wills after shooting a couple does this season as I mentioned above. After shooting my buck this week, I will never shoot anything but an Iron Will. Period. Long story, but I had a nice buck (and my first archery buck) come in to 14 yds. Had a very small window to take a shot before he hit my wind. I had to aim directly at his shoulder blade to avoid hitting a tree. I bought these broadheads to give me the confidence to take a shot like this and I probably would not with any other broadhead I have owned. The SB Iron will with snydercore shaft and collars did its job and is still serviceable to use again.

Onside shoulder entry, right on the “Y” of the shoulder.

Onside shoulder exit, completely shattered.

Far side shoulder. Made it all the way through shoulder but did not exit the hide. Both lungs deflated and the deer made it about 100 yds. Im not sure if other broadheads would have held up through this, but I am sure that I probably would not have been confident enough to take this shot. I will deal with the chipping and sharpen or replace as necessary. I spend too much time and money chasing these critter to have a broadhead fail.

And that's why I shoot them too. We spend thousands of dollars on all sorts of stuff that really in the end do not kill the animal. I do not want a piece of equipment to be the reason I don't kill an animal . I do not want it's failure to be mine.

I use one other 2 blade that is pretty beefy. It's done me well also.

At 1336 grains did it also pass through the hill?

A single bevel blade has less steel supporting the edge than a double bevel.

To picture this think of a pyramid. You could push down on the tip at a slight angle (20 deg) and in every direction the base spreads out and supports the tip.
Now slice the pyramid in half vertically. Now when you push down at an angle the tip isn’t supported from one entire side and you can easily tip over the pyramid.

That’s how a single bevel is.

Then folks will say, just increase the angle from say 22 deg. to 45 deg. that would increase the support. And it would, but it would make a very blunt edge. So some outfits will increase the angle slightly to around 30 deg. It helps some.

The issue isn’t just “steel”, it’s also mechanical structure.
Single bevel is a hard nut to crack. Especially when trying to consolidate materials and production.

Well that seems to me that TuffHead 300s apparently has its cake and eating it too recipe with the “weaker” edge single bevel and the correct steel formula to not chip.

Is IW and other making excuses with the single bevel being weaker or do they not have the right steel? If TuffHead can do it they can too.

Of course not. I’m still in shock it didn’t bounce off the deer. I just thought for sure that so many of the light/fast trad guys were right by saying fast is so much better for penetration than an arrow snailing thru the air at maybe 140 fps. Who’d a thunk
