Butch Vallotton is a renowned custom knifemaker and innovator and the first folder maker to use a blade?s thumb stud as a stop pin for the lock. The Vallotton Sub-Hilt pays tribute this innovation and is the only Spyderco to feature both a thumb stud and our trademark round hole. This hand-filling design features brushed stainless bolsters and a sub-hilt meticulously mated with contoured, polished G-10 scales. The CPM S30V blade combines hollow-ground primary bevels with a faceted flat-ground tip to provide a superior combination of cutting performance and point strength. A sturdy LinerLock mechanism and versatile four-position clip complete the package and make this one of the classiest production folding knives ever made.
