Notes on the Designer

Michael Walker is to the knife industry what Michael Jordan is to basketball or Wayne Gretzky is to hockey. He shattered established standards, venturing into uncharted territory and elevating the art of knife-making to new heights of innovation and modernity.

In 1980, the folding knife industry had few locking innovations, and only the traditional Back Lock existed. In 1981, Walker invented, developed, and ultimately trademarked the Michael Walker LinerLock®, adding a leaf spring that locked the blade open, making it a true one-handed folding knife. He also included a latch to keep the blade closed by utilizing the force of the internal leaf spring, preventing it from opening in the user’s pocket.

This innovation paved the way for modern cutlery, enabling numerous new designs and future developments leading up to today’s SubFrame Lock, Frame Lock, Flipper Folder, and ball-bearing-equipped IKBS opening systems.

Other inventions include the “Lake and Walker Safety System” (LAWKS), BLADELock, Ball Bearing Lock, and Tough Lock.

Some of the manufacturers he has collaborated with include Spyderco, Columbia River Knife and Tool, Schrade, Böker, and Klotzli.

Walker’s knives and designs have inspired many other custom knife makers, notably Bob Terzuola and Ernest Emerson. Terzuola credits Walker with teaching him how to make a liner-lock folder, and Emerson has stated that seeing one of Walker’s knives at a gun show inspired him to become a knifemaker.

Walker’s knives can be found at the Artifex Gallery in Taos and in the most prestigious collections around the world.
