Hi Inferno, glad you like 'em, thanks.
Yes, they are little neckers, tin knives, keychain blades, pocketknives, whatever works. Unobtrusive, like having a little box-cutter knife in your pocket. They are also excellent firesteel scrapers using the side of the bevel. I've replaced the weak-sauce factory scraper that came with my firesteel with one of these, lanyard-ed to it. And one of this pair has a bottle opener on the back. One long-time owner of a mini like these uses his to clear surface mounts for security installations, among a million other things. I usually carry the larger size in my jacket pocket.
Thank you for the compliment on my logo. Many folks don't get the reference. All my logos/steel-types are applied as an electro-chemical etch with a stencil. In the case of etching on a heat-treat surface, I skip the blackening step so that the logo is shiny against the colorized background.
