Has anyone tried these heads yet? They look good to me as far as length to width ratio. Do they just come in the single bevel? What is your thoughts on the single bevel? It would seem that a knife edge would cut better...?
I like the No Mercy heads. They're a nice design and shape, and hold a good edge, but Eskimos are still my favorite, and are hard to beat for their price! ;) I wouldn't move to No Mercy heads in place of Eskimos! :archer:
They are offered in a left single bevel, a right single bevel and double bevel. If you match the bevel to your fletching, studies have shown that you should experience increased penetration ;(esp. bone) all things else being equal. 3 Rivers and Braveheart have them now. Check out sponsers page.
I have been altering the shape of Zwicky Delta's and Magnus I's for years now to get the same shape as the No mercy (albeit, a tad shorter). They fly great, they sharpen up just fine. I think all of them are great heads. It all comes down to whatever turns you on.
Not certain, but it seems the No Mercy heads are a bit harder steel.

I bought a set just to compare them to my favorite broadheads , the STOS. I didn't hunt with the no mercy, but I will stick to my STOS, just because the STOS look like they are manufactured so much better and have such a precise cut/shape compared to the no mercy
Thanks Alex.B After your post I think I too will stick with the STOS, especially since I can get 'em real sharp real easy.
IMO, the right/left single bevelling on the no mercy broadheads is a lazy marketing gimmick since they weren't designed to properly accomodate single bevelling in the way that grizzlys and abowyer heads are. It would have been a simple enough thing for zwickey to have modified their heads to properly accomodate a single bevel, but they chose not to.
This is how they should have been modified for a single bevel (extend the ferrule flange to the unbevelled side of each edge)

of course it is a marketing thing. That is what everybody does...market things. If you don't think well of them, don't use them. Simple enough.
If you can make them better...go for it...then....market them.

So you agree that this is a marketing gimmick as well?
The original post asked what we thought of these heads, not whether we were planning to make our own broadheads.
I've had great luck with the new "No Mercy" Zwickey heads. I got a kick out of the story on the back of the package about how Jack came up with the name.
I shot 4 water buffalo and a bunch of whitetails with them. My wife also had good results with them.

flatbow MB, I thought offering the head in RW & LW single bevel was just a good idea. Jack isn't at all into marketing hype. Plus the fact that some folks don't think much of single bevel heads and probably never will. :)
I think the steel in Zwickey heads is superior to many of the other heads out there. I've heard it is something in the heat treating process. Haven't seen any in the "elf shoe" bowls of damaged heads in the african bowhunting camps I've been too.
The Zwickey construction design was patented in 1942 and has been copied many times.
Here is an interesting quote from a letter I received from Jack - "The Eskimo's cutting edge was shortened by the swept forward rear edges way back when to make it easier to extract from straw bales used at field shoots at that time."
I haven't used the single bevel type yet. Talking to Danny at 3Rivers peaked my interest though. He said imagine a string following the wound channel with a double bevel head. Now how much longer would the string be if a single bevel head rotated as it passed through? I've always had good luck with Grizzly heads, so I think I'll give them a try this year. Danny also had a way to get the sb heads hair poppping sharp.
There is a bunch of good heads out there that are more than adequate. I guess part of the fun for some of us is messing around with different ideas and dicussing them and there isn't anything wrong with that.
Denny, those are some great pictures! I've used zwickeys before and think their 2 blade heads are excellent. For single bevel grinds, I believe the modification I suggested would make a world of difference in their effectiveness.
