ARC is the first-ever multi-tool to include premium MagnaCut steel. The knife blade is made of CPM MagnaCut steel which maintains a sharp edge and excels in corrosion resistance, toughness, and ease of sharpening. The result is a knife blade that's perfect for everyday tasks as well as the harshest of environments. The DLC coating on the blade adds another layer of corrosion resistance. ARC also includes the highly-requested bit driver and thanks to FREE technology, each feature opens smoothly and is 100% one-hand operable. With 20 tools, removable pocket clip, four-pocket nylon sheath, and nine double-ended bits, the durable, practical ARC sets the standard for now and the future for premium multi-tools.
