The Launch 5 Auto Knife is an exciting new entry in Kershaw's automatic series that was designed by Emerson and USA-built by Kershaw. This handsome auto takes Emerson�?s tactical looks to the next level of refinement! The 3 2/5î CPM154 powdered metallurgy steel blade offers more uniform distribution of carbides„so it takes and holds an excellent edge. It also provides good corrosion resistance, wear resistance, and toughness. The blade is stonewashed for good looks and to hide scratches. To lighten the Launch 5's weight, the handles and integrated back-spacer are made of durable anodized aluminum. A machined texture on the handles provides a secure grip. It opens with a push button, recessed so that it is level with the flat of the handle. This is a safety feature and makes it harder for the knives to accidentally deploy. Left-handers can use their index finger instead of their thumb to press the blade-release/lock button. A reversible pocket-clip is included and a lanyard tie-off is built into the butt end of the knife.
