I have two. Great knives. As mentioned, they are made in Germany, very high quality. Known for their stag handles and also quality blades.
They're definitely keepers!
I stumbled upon a vintage Puma straight razor in a antique store in Nashille. It was in a cup with a bunch of junk straight razors. The only problem is it has a small nick in the blade. short story long, they are excellent knives.
