Survival Spear

It always bugs me when I see a "survival knife" advertised in sporting good stores. If you're going out hiking or on a boat, you need a good knife anyway. Why would you want another knife to carry around? Furthermore, these "survival" knives are pretty much crap. They often have hollow handles full of fishooks, an insignificant amount of fishline, a bandaid and maybe a match or two. Anybody that thinks they will survive based on the contents of a knife's hollow handle is fooling themselves. (Not to mention the inherent weakness of a knife whose blade doesn't go into the handle. NO WAY would I trust my life to something like that.) Instead of a lousy knife that I wouldn't even give someone as a toy, I propose: The Survival Spear. Much like the knife, you get a blade and a hollow handle. BUT, the handle telescopes out and locks in place forming a shaft of decent length. I guess the mechanism would work something like an umbrella, but naturally a rather strong one. With this spear you could conceivably kill something and eat it- you could spear a fish or throw it at something for example. You'll never do that with a knife unless you're Rambo. I'm not saying that this would be better than the contents of a REAL survival kit- namely a rescue beacon, food water and a GUN... but it's better than one of those stupid knives.
