The Walther PDP Tanto Tungsten Gray is a tactical knife that combines the qualities of Walther's successful Performance Duty Pistol. The knife's coated tanto blade is made of extremely sharp D2 steel and is perfect for demanding everyday tasks, during operations or during outdoor activities. The blade is 92 mm long and 3.6 mm thick and is locked with a stainless steel liner lock. It can be easily opened using the removable thumb button on both sides, which is based on the magazine holder of the Walther PDP pistol.

The full-size handle of the knife is equipped with G10 scales and a one-piece overlay made of GRP with the original Performance Duty structure. The loading grooves of the pistol slide have also been immortalized on the scales to provide additional grip. The knife can be carried safely and easily with the deep carry clip. A lanyard hole is discreetly housed on the rearmost spacer. The Walther PDP Tanto Tungsten Gray is part of the Walther PDP Folder family, which includes other models with different blade shapes and handle colors.
