Walter Wells "Blackie" Collins (1939 – July 20, 2011) was an American knife maker who designed and popularized the assisted opening mechanism and various automatic knife designs within the art of knifemaking. He is cited by other knifemakers and collectors as one of the most innovative knife designers in the world^[1] and was an author and the founder of what became Blade Magazine. Collins died July 20, 2011, in a motorcycle accident near North, South Carolina.^[2][3]

In 1981, Collins' designed a knife for Gerber Legendary Blades named the LST (light, strong, tough). The LST was the first knife to feature injection molded Zytel handles and featured a total of six parts. His next design was an assisted opening knife called the Strut and Cut; the design for which came from motorcycling. The Strut and Cut's opening mechanism was based on his Ducati's single strut which enables the knife to open and close easily.^[5]
