I don’t remember exactly but I was probably around 8yrs old. My great uncle was using a cheapo Japan made traditional knife to make some fishing lures. He noticed me watching him and gave the knife to me despite my mother not exactly approving. It had two blades, a small clip and smaller pen. Covers were plastic, made to look like checkered bone. The clip blade was bent. It was also discoloured from being heated with a lighter to melt the fishing line to finish the lures. Over the years I abused it further. When I stumbled across it in the garage a few years ago it was missing a bolster, covers were cracked and missing pieces, blades were not opening smoothly yet were wobbly. I put it in a spot to remind me to attempt to repair it. I finally got around to it and it is now back to work! I completely disassembled it, cleaned the parts, bent the clip blade back to almost perfectly straight. I turned the pen into a coping and reassembled the knife. She’s now sporting some homemade denim micarta covers with a thin red layer over the brass liners. No bolsters. Pins are now steel because that’s what I had. The clip blade always hit so I added a small piece of rubber on the spring where the tang meets when closing. Action is light but snappy. The knife surely wasn’t worth the time I put into it but not only was it a fun project and learning experience, but I can now pass it one to one of my boys, or my nephew one day.
