This dagger is much smaller than my typical daggers. It’s modeled from the Hudson Bay Trade Dagger that was traded to the Indians a long time ago.
Probably this one is a lot better than the ones they traded back then, because those were made of iron and case hardened, with a very thin veneer of steel. So if you sharpened those, you only sharpened one side, because then you’d always have steel on one side of the blade. If you sharpened both sides you’d get rid of all the steel and dull the blade.
