Walker has patented or trademarked more than 20 different mechanisms related to locks and composite cutting blades on pocketknives. Most notably, Walker is known for the invention of the
Walker Linerlock in 1981, which has since become the industry standard in folding knife mechanisms. What sets Walker's design apart is a long split in one of the liners which acts as a leaf-spring in the liner of the knife accompanied. This feature cuts down on mechanical stress. An additional feature of the
Linerlock is the addition of a ball detent. This additional feature eliminates rubbing and scratch-marks when the knife is opened and closed. Other inventions include the "Lake and Walker Safety System" or
LAWKS, BLADELock, Linerlock, Ball bearing lock, and Tough Lock. Some of the production companies he has partnered with include
Spyderco,
Columbia River Knife and Tool,
Schrade,
Böker, and Klotzli. Walker's knives and designs have inspired many other custom knifemakers, notably
Bob Terzuola and
Ernest Emerson. Terzuola credits Walker with teaching him how to make a linerlock folder and Emerson has said that seeing a Walker knife at a gun show gave him the inspiration to become a custom knifemaker. Walker's knives can be found at
Artifex Gallery in Taos, and in galleries and shows around the world. ==References==
