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.
