>>787760>what exactly is a survival knife?A knife that will not break on you. In a survival situation you may have to use your knife for something a normal knife is not intended for. It usually features a thick blade that is sharpened in a wide angle to keep it sharp as long as possible in heavy use. You should be able to fall small trees with it. The blade lenght is not so important for hacking stuff with a knife is very unneffecient way to work compared to batoning.
Many knives are marketed as survival knives, but most of them are not. Once you learn about knives you can just look at the knive and tell if it's good for survival use or not.
Often you hear "The best survival knife is the knife you have with you" is like saying the best car in the world is the car you own. Unlike the with other knives the best survival knife is not what "works" for you either.
It's okay to practice with a survival knife, but really it should always be a backup knife, not your primary knife. You can easily loose your primary knife and besides, why would you want to use a knife that sucks in every situation except survival one?
