The SOG Specialty Knives & Tools A03-P Architech Damascus starts with the combined technical knife excellence and exquisite high-end collectability of an Architech knife and finishes with a stunning Japanese Damascus steel presentation. Japanese Damascus uses a core of San Mai VG10 and (15) layers of nickel and stainless steel on either side. The steel is forged and folded again and again to produce this striking pattern. Then finally the knife is acid etched to bring the pattern up clearly (carbon and nickel become black). The polished finish, 3.5-inch straight edge, folding blade has a clip point shape that allows a quicker and deeper puncture upon insertion, sharpens easily and makes quick work of any task. The blade of this limited knife provides lightning-quick, one-handed opening and closing capability thanks to the special Arc-Lock for ambidexterity. The ergonomically contoured and well-balanced handle has a black finish and is made of a high strength, titanium and textured carbon fiber that will fit comfortably in your hand. A reversible pocket clip extends from the back of the handle, allowing the Architech Damascus to sit low in your pocket for the most discreet carry possible. This pocket clip can also double as a money clip. This knife has a closed length of 4.5-inches, overall length of 8-inches, blade thickness of 0.15-inches and weighs 4.5-ounces. The SOG A03-P Architech Damascus Knife comes with a limited lifetime warranty that protects against defects in manufacturing and materials.
