The Spyderco Police 4 has been a staple in the Spyderco lineup since it was released in the 1980's. This Police 4 Lightweight follows in that tradition, but in a lighter, easier to carry form. The Police 4 Lightweight uses textured FRN handle scales to save nearly an ounce and half versus the traditional stainless steel handled version. The flat ground K390 blade makes this one an amazing slicer and allows for easy maintenance. Specs: Weight: 4.2 ounces Overall Length: 9.97" Blade Length: 4.39" Blade Steel: Bohler K390 Blade Thickness: 0.118" Blade Shape: Spear Point Blade Grind: Full Flat Blade Finish: Satin Handle Material: Blue FRN Lock Type: Back Lock Opening Mechanism: Round Hole Pocket Clip: 4 posiiton Country of Origin: Japan NOTE: K390 is not a stainless steel. Proper care such as keeping blade clean, dry and oiled are necessary to help maintain the finish. Tarnishing, rusting, pitting etc are not a flaw in the steel, but simply a characteristic of this superior tool steel.
