Here is a new "survival knife/spear head" I have been working on this winter.
They are made out of some of the hardest stainless I have ever got a hold of. I burned up 3 HS drill bits trying to drill one hole in the first one. This is why I had to go with the tie on notch.
I wrap the tang with 1/8" diamond braid nylon cordage. 16' works real well. It can be unwound to use for ataching the spear head to a pole/stick. The cordage is also a major plus in many other situations.
Let me know what you all think.
