In most scenarios a knife is the single most important tool you can have in a wilderness environment. In the hands of a skilled practitioner it yields shelter, water, fire, food and many other vital elements that keep you alive. Therefore, if you do something to break or damage your knife, it could be a mistake that costs your life. I say this as a word of caution because attaching your only knife to the end of a stick and then swinging it around aimlessly is a recipe for ruining it. It is not for hunting, and most definitely not for spear fishing because those activities will leave you with a blade that is shattered, cracked, dulled and essentially useless.
