Repro of a concept.
For starters a trapper would need finesse to use it.
Consider the environs. As in freezing. Would anyone are to hold such? For what purpose? Not to skin with. The design fails.
For a repro of a concept today it could be hardened (case hardened or sugar used or modern surface hardening compound allowing it to be used for flint and steel fire starting.
Fleshing hides in the cold takes a toll on hands. Tiny tools after aren't quite entertaining.
Furs are not prime until it has been cold a while.
Whoever stated trapper knife should have tried civilian strike a light knife or something.
They put it out of context .
then try to give it an age...
A home smithy (and most homesteads had a forge ; if not one was near somewhere. Small forges about as big as a common kitchen sink) would delight in an old file to make such an item. Good steel.
Pits are not good on a blades edge.
What trapper would want even a tiny knife to have a notch or more in the business edge of a hardened blade edge when pits are encountered?
That would require more work. Something not needed. Let alone paid/traded for to create.
Finally, how hot a spark does it throw?
If it isn't the hottest no self respecting trapper back when would want anything to do with it.
(Look up flint and steel strikers for varieties.)
