OK, I'm going to take a chance and post this here. I saw this when I was a kid but haven't seen it since. I've looked for it many times, and it should be around here somewhere, but no luck finding it. Also, it really is more of a letter opener than a knife, but it's so unusual that I want to share it. And, since I can't find it, I did a quick sketch to show what I remember it looking like. You see, this is made from
aircraft wire. Don't know what aircraft wire is? Read on! When my father joined the Navy he became a Aviation Machinist Mate. He subsequently went to "90 Day Wonder" school, was commissioned, and became a Lighter than Air pilot. But back to the AMM rating... Back in those days the Navy still used Stearman N2S biplanes as trainers. Biplanes use aircraft wire for bracing between the wings. It's flat, wide, and tapered, kind of like a double edged knife blade. Someone (don't know if it was my father or not) had taken a piece, ground or filed a point on it, and wrapped part of it with some kind of cord to make a handle. I think the cord was treated with some sort of sealant -- probably the aircraft dope that was used on fabric covered airplanes. Oh, I'd give almost anything to be able to find this again!
