Even though the large Otter Mercator knife wasn't designed to be an Army knife, it quickly gained acceptance in Emperor William's army. This was also the time that the name "Emperor William Knife" was created.

Simple, functional, and robust – the Mercator knife has offered these benefits for over 100 years. Today, the knife is used worldwide and distinguishes itself with its narrow, rugged design in everyday life.

This Mercator knife is completely stainless. The knife is lockable, which facilitates safety when working with it.

OTTER knives have been manufactured and sharpened in Solingen, Germany, since 1840, using traditional methods of meticulous handcraftsmanship.
