The Puma Heritage Series are based on some of the best-selling slip joint knives ever in the history of Puma. Originally introduced in the early 1970’s, the Heritage knives were among the most popular Puma slip joint knives ever made. The Senior has an overall length 7.2", a blade length of 3.0" and a total weight of 2.7 oz. This is an excellent knife for every day carry and also features a spey blade. The hollow ground satin finished blades are made of 1.4116 German Cutlery steel with a thickness between 2.5 and 3mm. Each knife also has a Rockwell hardness of 55-57. Our EDC knives have features such as brass bolsters, belt loop ring, and spey blades. When it matters, would you prefer German steel or Chinese steel?
