    Pretty cool knife. You should see my knife and scabbard/sheath. I must say my knife looks cooler. On the contrary, your's looks a lot sturdier, which is something I like to look for.

    Your knife looks a little better and the handle looks a lot more realistic, but yours doesn't look very strong and it looks hard to make.
