Features: length overall 5.80" (147 mm) blade length 2.35" (60 mm) blade steel N690Co length closed 3.45" (88 mm) cutting edge 2.08" (53 mm) weight 1.9 g (54 oz) blade thickness 0.1" (2.8 mm) handle material FRN A collaborative effort of Danish knifemakers Jens Anso and Jesper Voxnaes, the Pingo was specifically designed to conform to the knife laws of Denmark, which prohibit both lock-blade folding knives and all forms of one-hand-opening knives. The heart of the Pingo is its distinctive sheepfoot blade, which is ground from Böhler-Uddeholm’s premium N690Co stainless steel. The blade is designed to meet Danish legal length limits while still providing a very functional and versatile cutting tool. Its Trademark Round Hole clearly identifies it as a Spyderco knife and provides a handy purchase for two-handed opening, but the hole is purposely small to prevent one-handed blade-opening methods. Similarly, its stout notched-joint mechanism is powered by a strong spring that helps hold the blade securely in the open and closed positions, supporting its safe use as a cutting tool while precluding one-handed opening.
