The Spyderco Yojimbo was originally designed by personal defense trainer Michael Janich. It has since evolved into the Yojimbo 2 with a couple of slight modifications. Its ergonomics make for a comfortable fit in the hand by ensuring maximum surface contact and positive control. The Spyderco Yojimbo’s big brother, the Yojumbo, is an even larger knife but based on the same premise. Available in different blade finishes and a variety of aftermarket parts, this knife is sure to fit anyone’s style.
