Puma Knives Tac 1 fixed blade designed as a survival or military style knife by Helmut Jermer. Features a satin finished chisel ground tanto blade, notched thumb rest. 3/16" blade stock and 1-1/4" blade depth, full tang construction with black thermoplastic scales. The sheath is cordura with plastic elements sewn to it. It is in a very good condition but two plastic elements made of bent plastic cracked in half, anyway the "dog collar" type clip works fine due to a cordura strap attached to plastic. 
The "proof mark" (a small dot) is present on the rear side of the blade.
From puma knives web: "This small dot is the "proof mark" from a Rockwell hardness tester. Using a diamond-pointed needle, every blade is tested for hardness. This needle causes the proof mark that is a symbol of a PUMA and is your personal assurance that your knife is the PUMA quality promise. 440 A steel - the steel used to make PUMA German knives is the best knife steel in the world." 
Specifications: Blade length: 6-1/2". Overall length: 12-3/8". Made in Solingen Germany. No box.
