This is a survival knife for US Air Force pilots. It's a long-lived knife, used from 1961 to the 2000s. While the manufacturers were primarily Camillus and Ontario, this particular item is made by Camillus. The sheath is constructed more robustly, with metal plates covering the tip and the entire blade storage area on the back. This is an excellent knife that served as the prototype for later survival knives. This knife has only been used for display purposes since I acquired it, and has not been sharpened or used outdoors. However, the sharpening stone was not included when I purchased it. Total length: 24.5cm Blade length: 13cm (from the hilt to the tip) Handle material: Laminated leather washer I am selling this item as part of a decluttering effort. Please understand that this is a used item before purchasing.
