Spyderco Vallotton

Butch Vallotton, like most knifemakers, started making knives as a hobby, had to start selling knives to pay for his hobby. His collaboration with Spyderco called the Vallotton Sub Hilt Folder features an ambidextrous thumb stud that both opens the blade (in addition to the Spyderco Round Hole) and doubles as a stop pin keeping the blade from rotating open beyond the locked position.
