For more than four decades Heckler & Koch, Oberndorf, is one of the world's leading maufacturers for police and military weapons. Almost every western Special Forces Unit is equipped with H&K guns and rifles. They also have an equally impressive range of fixed and folding knives utilising the same precision and expertise.

The Grey Impact has a bead blasted, plain-edge drop point blade and a robust handle made from 6061-T6 Airplane Aluminium with a textured "Reptile Grip" insert to enable a perfect grip. It also has a pocket clip.
