Thanks, it's a really nice little knife with useful blades.
Pulling alerts at Titan II missile silos, we were required to carry and maintain our own copy of a 700+ page technical manual, 21M-LGM-25C-1 Operations Manual. Was issued a heavy leather satchel grip to carry it in that I still use for important papers. Going through it the other day and found the small lockback I carried while pulling alerts. The stamp is a Smith and Wesson logo, so it must be good!

Held at certain angles you can tell I tweaked the end of it a bit using it to pry. Not very valuable money wise but brings back memories of my glory days and means the world to me.
