Sorry, I guess I didn't specify. I am writing a paper of how I made my anvil and forge, and learning arc welding in the process. The knife I'm making now I'll give to my principal to show that I can make a knife. Then, my parents just have to sign something saying I did learn the forge a knife.
Below is what I'm thinking for the tang(bottom drawing). About a 1 in. width with two half inch holes on either side. The blade shape will just be a simple bowie shape, if you're wondering. Then, the cast handle (top drawing) will have the guards a part of it, like you mentiond. Sorry, I'm not a very good artist.
