The Efficient includes all the high-performance features and benefits that savvy knife users have come to expect from Spyderco knives. The heart of the Efficient's compact, ergonomic design is its full-flat-ground drop-point blade. Precision machined from 8Cr13MoV stainless steel, its broad profile and PlainEdge cutting edge offer outstanding edge geometry for low-friction cutting performance. An index-finger choil at the base of the edge provides a comfortable purchase for a forward grip, allowing enhanced control during precise cutting chores. To ensure swift, one-handed opening, the blade also proudly features Spyderco's signature Trademark Round Hole.
