I had mentioned in the past about an unscrupulous person from the United States who had made up fake Puma springer's and marketed them in old Puma razor boxes. Here's one in genuine gold lip MOP that I recently acquired.
Because I have a mint real one and I know who made the fakes. He also made some fake Hen and Rooster, and others. I think anybody who collects Puma knives whether they be automatics or not would know that Puma never stamped their knives like this.
