I recently made this knife out of a copper tube. It's work hardened and keeps a pretty nice edge on it, works well as a throwing knife. To get the shine to stay on it, I polished it with coarse sandpaper, then fine, then used 2 different rubbing compounds to get the scratches off, then did 3 coats of clear coat lacquer.
The handle is made out of pine I believe, or some other common wood, I'm not too sure on that. But I used a 1x1 inch piece of the wood, and used about .3inches of wood on each side of the blade handle. The handle is coated in a pecan color wood stain with a smooth finish in it.
The blade is actually soft 1/2" copper tubing, about 10.5" of it. I work hardened it with a ball-peen hammer so it flexes, but doesnt really bend. The blade length is 6", while the handle is 4", for a total length of 10". And yes, the blade is full tang, if you havent already figured that out.
I forgot to take pictures along the way, so I snapped a few pics of the finished product with my camera phone, explaining the moderate quality on them.
All in all, its the best knife out of the 2 I have made (not much to compare to, I'm planning on making more) and I probably could have used a nicer looking thing to bind the handles together than gorilla glue, but it works.
