The Police 4 is the largest member of Spyderco's select family of lightweight knives featuring K390 MICROCLEAN tool steel blades. Ideal for extreme cutting challenges, it combines the toughness and superior edge-holding characteristics of K390 with all the proven qualities of this highly refined design -- including the low-friction edge geometry of a full-flatground, PlainEdge blade, a fully accessible Trademark Round Hole, a high-strength back lock mechanism, and a four-position pocket clip.
The K390 is ridiculous and holds an edge through anything I've thrown at it. And by stropping it regularly I have been able to keep a working edge easily without sharpening. It carries remarkably well for such a huge knife. Great ergos no matter how you hold it. Great price and fast shipping from National.
