I found a Victorinox 3" serrated paring knife at Goodwill today. I considered making a Kydex sheath for it, but the sheath would weigh more than the knife, which just seemed WRONG in an UL way. I had a standard knife edge guard as you would find in a kitchen store, so I cut a piece from that, profiled the end to match the knife handle end and drilled a few holes down the side. I took a spare hank of Glowire line, pulled the center strands out and lashed the edge guard with it, leaving enough for a neck lanyard and finished up with a mini toggle to make it adjustable and it will pull loose it I get hung up on it.
Total weight: one ounce. Total cost: about $5. Assembly time: about 15 minutes. Recycled content: 90%.
