Thanks for the comments guys. I'm sneaking my latest in here so I don't become a thread hog:
I started out thinking I'd use a nice whitetail shed for the handle, but one thing led to another and the knife I finished looks nothing like the knife I started out to make.
This one is a real recycle job. Handle came from an old piano, copper from an old computer heat sink, and an old Nicholson file for the blade. On to the next...
