IMO Eick did sell a lot of parts to various manufacturers of bayonets. My experience in large part is limited to fireman's pieces but I own & have owned a number of bayonets by smaller cottage type makers that all have distinctive Eickhorn parts & of course Eickhorn quality. If they did it with bayonet parts, it's quite possible they did it with dagger parts as well, right?
Never seen a Hack KM or even heard of one. I'd imagine if there was one, it would bring a pile of cash.
