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.

Ed Schempp, a wheat farmer, metallurgist, and renowned knife maker, created the Persian Folder by blending classic Western elegance with exotic Eastern charm. Traditionally, Persian knives are fixed, but Ed reinterpreted this typical shape in a folding knife.

Characterized by curved and harmonious lines, the Persian Folder 90 mm stands out for its black Micarta scales combined with polished stainless steel guards. The handle features a series of finger choils that allow for a firm grip and total control of the blade. The blade, inspired by the East, has a pronounced belly and an elegant upward-pointing tip.

Made of high-performance VG-10 steel with a concave grind, the blade measures 89 mm and features a prominent “hump” above the opening hole, ideal as a thumb rest. The clip allows for right-side tip-up pocket carry. A milling on the locking mechanism, known as the David Boye Dent, increases safety by preventing accidental unlocking during a firm grip.

A pollywog represents metamorphosis in the animal kingdom, adapting and changing its form to survive in its environment. The same principle applies here. The Spyderco Poliwog CLIPIT® thrives in a small-knife-friendly environment while keeping the features necessary to excel in a harsh, heavy cutting and performance setting. Its distinctive opened-ended Ball Bearing Lock™ exposes the knife's inner workings for easy cleaning and rates as one of Spyderco's highest strength locking mechanisms. Pulling back on the ball unlocks the blade ambidextrously from either side of the knife.

The hand settles on the curved handle positioning the index finger into a choil that optimizes control and generates less fatigue and pressure on the hand during cutting. Made from VG-10, the blade has a hollow-ground edge with a weight reducing swedge-grind extending mid-spine to the tip. It is available in PlainEdge. Its ambidextrous wire-tension pocket clip sets the Poliwog tip-up in the pocket.
