Sorry for the long thread:
I make them here in Ca. On HAAS machines. The joint is not heat-treated and stays "springy" I have used the head as a pry-bar during testing to pull apart split logs and move things that weigh much more than I do. No problems.
I do not suggest these kinds of uses and would not be able to warranty the Hawks should they be used as a lever under severe conditions. It is not THE ultimate cure-all. But it does what it was designed for very well. It is far more durable than many other hawk handle materials out there.
They are sharp before the powder-coating. A couple of minutes with a stone will make them razor sharp.
The Tactical Hawk-Spike is made from 3/8" thick 1050 high carbon steel. The edges are hardened, and tempered. But the handle is left unhardened for its shock absorbing ability.
The Hawk is powder-coated tan over its entire 16.5" length. The head is 7.5" long with a 3.5" Edge face. The beard also has 3 inches of sharpened edge for hooking moves. The spike is 3.5 inches long from the center of the hawk. The spike is an inverted Americanized Tanto shape and is sharpended all the way around. For a total of 9 inches of sharp edge.
The Handle scales are 6061 T6 Aluminum that has been MIL Spec Type III Hard Anodized with a greenish tint.
It comes with a proprietary Kydex sheath made for K5 Tactical by The SheathMechanic. The sheath is Jumpable, ambidextrous, and uses short Alice/MALICE clip attachments, making it MOLLE/Strike compatible.(Not included) And most important of all, it is MADE IN THE USA!
The only drawback is the sheaths are 3 to 4 weeks out for delivery.

Thank you very much for your comments and questions. They are important to me, and your concerns are definitley taken to heart. I want to make(and believe I am making) the best set of tomahawks out there at the best value. My plan from the begining, when I was penciling these out a year and a half ago is to make these in a way that they are affordable and available in quantity.
