The Faithfull Heavy-Duty Retractable Snap-Off Trimming Knife has a two function button that enables the knife to be used as an auto-retracting safety knife or as a fixed blade knife. The first button reveals the blade when pushed forward and is sprung to retract the blade when released. The second button is a ratchet-lock blade slider that allows multiple blade positions for custom cutting depths. The aluminium body is fitted with a dual compound ABS and TPR soft grip for comfort and features a hole for attaching to a lanyard. The blade holder is made from stainless steel for durability. The end cap is removable to allow loading of new blades and features a handy slot for snapping off blades safely.
