Designed by noted personal-defense trainer Michael Janich, the Yojimbo 2 is an evolved expression of his original Spyderco Yojimbo design, which pioneered the application of the Wharncliffe blade in tactical folders. The refined ergonomics of the Yojimbo 2 complement the natural contours of the hand, ensuring maximum surface contact and positive control. They also encourage a thumb-forward grip and make the 3-1/4-inch CPM S30V blade a natural extension of the hand.
