Roughed out one head.  Needs a little clean up before heat treatment.  [attachment=1]

Are you going to put a helical twist to it? Heat it up a bit perhaps?

What material did you make that out of?

I'm curious also?  I would guess O1, it's easy to harden.

I'd be concerned about that needle point that it might bend if a bone is hit. I usually add a Tanto style point(I think that's what it's called). If I can find a pic I'll post it.

A2 steel is also good. Air quench to harden, no messy oil.

Thats for sure. S7 is awesome also, especially for broad heads. But these fancy tool steels are a bit fiddy to heat treat properly. I can't imagine treating them without a temperature controlled oven with ramp/soak function.

This is a single bevel Abowyer that I made a Tanto point on. I not only make the point blunter but also sharpen both sides of the point on both sides of the head. With a single bevel and Tanto point if you hit a bone the point rotates splitting the bone instead of just sticking in and is less apt to bending.

Single or double bevel?

The steel is 1075.  I tested hardening a scrap piece using a propane torch and brine quench.  A file slides over it without a mark.  I'll use canola oil for future quenching.

Not decided on the tempering temp yet but maybe 500*f.

Pat, I planned on a single bevel but at .100 thick it might not work.  I'll try it though.   That's what this one is all about.  Agree on that  needle point!  I'm also thinking about wrap.  I don't have sinew and artificial sinew truly doesn't have much resemblance to the characteristics of the real thing.  Silk??

Keep at it Michael 👍🏼

Have fun Mike...

Keep us posted..

I like it! What thickness is that?

Mike, any strong, thin thread will work. Once set in glue the resulting wrap is stronger then the two parts separately. You don't want a bulky wrap though or it will impede penetration.
If you want to try sinew I'll be happy to send you some. 

Kenny,  it's  .100.  I think a little too thick. 

Pat, thanks for your generous offer.  I think I'll go with the silk.  Got quite a bit of it in the fly tying kit.

Pat B that is an awesome looking point!

Kenneth, I really like those Abowyer trade points and with the addition of the Tanto point they are awesome.

S7/bearcat is really good for shock


Longcruise 500 in Moms oven, sand it shiny and Bake it in the Oven.
I've done this many times on small parts with a color chart, no  big deal
Cutting torch or rosebud tip for heat treating and bake for temper.
