The Faithfull Lock Back Utility Knife features a lightweight nylon casing with a durable metal folding mechanism and quick release blade change. The folding blade holder allows the blade to be securely stored inside the body of the knife but can be easily pulled open and locked in place ready for use. After use a simple press on the release lever allows the blade to be returned into the body of the knife for safe keeping. Changing the blade is carried out by pressing the side release button on the blade holder and then pulling the old blade out, the new blade can then be simply slid into position ready for use. The blade holder also incorporates a useful thumb pad for precise pressure control when cutting. The lightweight, compact size of this knife makes it ideal for storing in a pocket, but also has the added convenience of both a belt clip and a lanyard hole. This knife uses standard trimming knife blades which are readily available. Folded size: 100mm (4in). FAITKLBN
