The Sheffield 12170 Alloy Series Mechan 9-in-1 3 Drop Point Folding Knife has all the features and more to make this your prized everyday carry knife. A black oxide bonded, partially serrated, 420 Stainless Steel knife may be the main attraction here, but the Mechan offers so much more than a blade. With additional features such as a five wrench set (4mm-12mm), slotted screwdriver head, bottle opener, and 2 ruled edge, the Mechan is a vital tactical knife to have by your side for nearly any situation. As with any EDC knife, comfort and carry are key. The Mechan delivers with a contoured bottom edge to fit comfortably in your hand, while a pocket clip and lanyard opening give you plenty of carrying options. Sheffield knives are backed by our industry-leading Lifetime Warranty.
