The development of the TOPS Wilderness Guide 4.0 knife is a result of long-thought and substantial input from professional Outdoorsmen. With some 16 million backpackers just in the USA, plus all the Mountain Bikers, Trekkers, Sea Kayakers, Climbers, and Survivalists, TOPS realized that no one knife would do it for all. Therefore, this design is highly functional, using 1/8" thick, easy to re-sharpen, 1095 High Carbon alloy. It has an exceptionally wide blade (1 1/2") with a blade length of 4 1/2", and generally suits a wide variety of outdoor requirements. Leo Espinoza designed a very functional handle that fits the hand well with excellent traction and a slight recurve at the back to keep the grip secure in wet conditions. This is a great addition to any outdoorsman's gear.Includes:USA made emergency whistle (126 DB)Dog tag sized signal mirrorSteel snap linkFresnel lens12 feet of trail marking tape (hunter's orange)Liquid filled compass
