The Zero Tolerance 452GL is a stunning, relatively large pocket knife. With a 10.4 cm blade and a total length of 23.4 cm this is definitely a knife that will be favoured by people with large hands. This knife is designed by Dmitry Sinkevich, a custom knife maker. He initially designed the limited edition 454 for Zero Tolerance. An incredibly popular model, but soon no longer available. This 0452GL is, in terms of size, similar to the 454, but the material for the handle and the finish of the blade are different.
