The streamlined Filter is a rugged looking everyday carrier with machined good looks and smooth function. Complementing the all-steel design is a handsome, non-reflective black-oxide BlackWash finish, giving the Filter a unique well-worn look that helps to hide general wear and tear and improves resistance to corrosion. The 3.2” blade is crafted from high-performance 4Cr14 steel, making it highly stain resistant. The stainless steel handle is finished with the same coating, giving the knife a uniform look front to back. Equipped with SpeedSafe opening technology, the Filter can be quickly and easily operated safely with one hand. A secure frame lock keeps the blade open during use and allows for easy closure for storage. The Filter includes a deep-carry pocketclip for a comfortable, discreet carry. Perfectly at home in machine shops, factories, warehouses, construction sites and garages, the Filter is a masterful tool for every worker.
