I put the final touches on this one today. handles are deer jawbone, nickel pins, brass standoff pins, brass pivot pin washers and a aged carbon blade riding on teflon washers. Not perfect, not finely finished. left some scratches, dings, and there are cracks in the jawbones as they were found from a very old natural kill out in the woods. My only concern with this build was for it to look primitive. The blade was made from an 1840's butcher knife.
