Renowned personal-defense trainer Michael Janich is credited with popularizing the modern Wharncliffe blade design with an eye on tactical applications. This unusual blade design culminated in his most recent creation — the redesigned Spyderco Yojimbo 2.

Spyderco is known for taking risks on knives with odd-looking designs, and the Yojimbo 2 is no exception.

The most notable part of the whole knife is the 3.11-inch Wharncliffe blade. A Wharncliffe blade is defined by having a completely flat edge with a spine that tapers to a piercing point. Both of these attributes make the profile excellent for everyday tasks… and self-defense.

Using S30V stainless steel, the blade holds an edge well and resists corrosion without much issue. Like nearly all Spydercos, the knife opens quickly and smoothly via the patented Round Hole.

The G-10 handle scales may look thin and uncomfortable, but that would be far from the truth. The scales conform to the natural curves and dips of the hand to ensure maximum control and comfort. This is essential for all types of emergency situations.

Last, but certainly not least, the knife uses Spyderco’s Compression Lock, which keeps the fingers out of the path of the blade and provides excellent strength when coupled with nestled stainless steel liners. The knife also comes with a four-position pocket clip.
