Spyderco is fortunate to have collaborated on numerous knife designs with custom knifemaker Frank Centofante over the past decade. Frank's lifetime of experience in designing and crafting knives guarantees style and function in a gentleman's folder.

Spyderco's Centofante4 folder represents the evolutionary refinement of previous Centofante/Spyderco collaborations. Its thin-profiled fiberglass reinforced nylon (FRN) handle is furrowed with grip enhancing channels and inset with a Palladium silver Spyderco logo bug. Adding security and ease of deployment, the back-lock is positioned mid-spine. Cut out of the locking lever is a David Boye Dent, diminishing the feasibility of gripping the knife handle tightly enough while cutting to unintentionally release the lock. The Centofante4 features a Wharncliffe VG-10 steel blade that has both a hollow-grind and a non-sharpened spine swedge-grind. Prominently rising above the Spyderco Round Hole is a crest for the thumb keeping it in controlled contact with the blade. Right-hand steel pocket clip positions the folder for tip-up/tip-down carry. Nested steel liner in the handle creates rigidity and a foundation for the clip's screw attachment.
