Spyderco YoJumbo C253G Black G10 pocket knife, Michael Janich design

The Spyderco YoJumbo C253G is a characteristic pocket knife, designed by Michael Janich. He is a respected expert in the field of self-defence. The hollow-grind blade with typical Wharncliffe shape is locked by a solid compression lock when opened. A lock we have seen before on the popular Paramilitary 2. This lock is similar to a linerlock. The difference, however, is that you can unlock it on the spine of the handle.


The YoJumbo is the larger version of the Yojimbo. Spyderco made it 20% larger. The handle is made from G10. The stainless steel liners on the inside were kept as compact as possible and were milled in the G10. As such the knife weighs next to nothing. The pocket clip can be attached in four ways. It truly is a friend to all.
