"A guard on a bush knife is in the way and detracts from many operations. It prevents the use of a simple, secure deep sheath. Some people prefer a guard for fear of slipping forward onto the knife edge, but unless the knife is used for stabbing, the hand should never slip in this way. In all my years of instructing I do not recall an injury due to the lack of a guard." - Mors Kochanski, Bushcraft: Outdoor Skills and Wilderness Survival
