I have a Hirschkrone hunter's folder, just like Puma 945, but with a birdhook. It is not old because backsprings and locking lever are stainless, though a bit darker than the blades, and the name is not stamped but just painted. Only Rostfrei Solingen are stamped in the blade bases. However, the knife works flawlessly. As I understand, Hirschkrone is not a company name, but a trade mark. There a few mentions on this name in some threads, but nothing definite. Who could tell me what is it and whom does this trade mark belong?
