Sure, I've seen dozens of these with various applications. They're nose hair trimmers. You can do both nostrils at once then use the brass nib to swab them clean. They're also a farm tool used for castrating livestock. Both testicles can be removed at the same time. If one gets stuck the brass nib is used to persuade it loose. It's also used in tissue transplanting. Strips can be cut from the scalp and relocated. The brass nib helps lift and place the cut strip. Same goes for skin transfers from the buttucks or legs to other areas where they're needed. Leather workers also use this type of tool to cut strips for belts. Chefs use them too when precisely consistant sized chunks of "whatever" are needed. The brass nib is used to aid in arrangement of the pieces for presentation. They also, obviously, use them for slicing bread. When toasting the slices, if one hangs in the toaster, yep, you got it, the brass nib aids with its removal. Mechanics...now there's some interesting applications. The better known of these applications is the cutting of strips of a highly specialized heat tolerant sealing tape used for muffler and pipe repair. The brass nib helps position and work the tape when the pipes are hot. My favorate use of all though, was it's original purpose. Believe it or not, these were designed for some of our country's earliest school teachers, when crayons were still made by the teacher in the classroom. They had a unique wax/tallow extruding device they were able to add different colors to. After the wax/tallow/color mixture was extruded the knife was used to cut evenly lengthed crayons. The brass nib was used to clean the extrusion port between runs of different colors.
Well, these are just a few of the many applications I know of. Perhaps others of you know some more. Godogs57, you should be able to make about ten of these in a few hours for $10 or $20 bucks apiece. No prob!
Good luck, Phil
