Puma made some of the best production knives in the world up until they were sold in the early 80's. Since then the quality has dropped dramatically. I bought one of their stag handled four star knives out of curiosity a couple of years ago. The stag was lousy, fit and finish was well below average, and it didn't hold an edge well at all.
My advice - steer clear of Puma. But... if you ever run across one of their older knives in the green and yellow plastic box - jump on it. Those pre-early
80's Puma's were outstanding knives.
