Only eleven centimeters long when open and 63 mm long when closed, the Walther PPQ weighs about as much as a standard letter. This tiny knife lives up to its name in another way too. Like the famous Walther PPQ pistol it has a miniaturized Hi-Grip surface finish. The 48 mm black coated spear point blade is made of 440C high-performance steel and must be opened with a second hand using the nail groove. Thus you can carry this two-hand opening knife on your key chain at all times and have no problems with the law. It attaches with a stirrup-like ring.
