My GP 100, with a 5" boot knife I made myself in 1980. Blade came from an old file, copper parts were scrap from work, and the handle slabs are from some rude slabs of cherry wood that I found in the barn where I lived at the time. I never made a sheath for it; it only gets used as a letter-opener.
I didn't have a forge to work the blade with, did what I could with a propane torch, so the heat-treatment is way off; some spots soft and others hard.
