I got this yesterday. It is a Puma "White Hunter". It was in my late father in law's hunting gear, all of which was left to me. He was more of a duck hunter than deer hunter, but he did deer hunt some. Unfortunately, he had stopped hunting by the time my wife and I met. He passed away last year, and we are slowly going through things.
I did some research on it, and it turns out that this design was developed in the mid 1950's as a collaboration between members of the East African Professional Hunter's Association. Basically, a group of PH's (professional hunters) in Kenya got together and came up with this design, which they felt was the best general purpose African bush knife and worked with Puma, in Solingen Germany to produce the knife. From my research it took on quite a following in the 60's, 70's and 80's and some of these were apparently popular for soldiers to carry during the Vietnam War. Its size is probably better suited to use on larger African animals than whitetail deer, but I may use it to break down the next deer I get to see how it does. Generally, for deer I prefer a blade of about 3 inches or a little shorter.
