I made my own hunting knife from a piece of tool steel. The steel that I used was from a saw blade that was used to cut 1 foot thick by 4 foot wide steel slabs. It's really some hard steel and took a good while to get it sharp after I got it into the shape I want. It has a 4 inch blade, handles made from a 7 point I took in Sumter county, Alabama a few years back. I like my homemade hunting knife. Here's some pics of the finished knife.
BTW, this is the first knife I ever made. I got a few pointers from someone on how to grind it down without losing the temper in the steel and how to attach the handles with some brass rod, other than that, I figure it turned out good for my first knife. One thing's for sure, it's the sharpest knife I ever owned.
