After reading the "world's strongest sword" thread, I was struck with inspiration. As long as there's an interest in re-hashing ancient weapons, why not update one of the oldest weapons in human history - the spear. I think nowadays, it is one of the most under-appreciated weapons. The spear was the hunter's weapon of choice since the stone age. Heck - as a point of reference, the spear *may* have been responsible for the extinction of numerous forms of ice-age/post ice-age megafauna (IE - the mammoths and so on). The spear was a pivotal tool in numerous wars for centuries. I even recall one relatively modern battle where a modern army (armed with guns) was defeated by another army (armed with spears) but I can't remember which one it was. Ok----they were overrun, but still.....they were overrun by the spear. at any rate, there have been a number of noteworthy advances in the manufacture/application of materials, as well as huge improvements in tools that make weapons more effective. I say this----think of the spear. The spear is much deadlier than the dagger/sword due to the length of it's "reach". It's capable of both slashing (when used correctly) and stabbing. It is a melee weapon AND a projectile weapon (like any modern day missile or gun). Why not update the spear? First off, the spear should be constructed of an unbreakable material. The downfall of the wooden spear was that it could be easily broken because it was made from wood, The unbreakable material it's made from should be extremely light weight. When hurled, it should have the same sort of guidance system as many of the modern day "guided munitions" (IE - wire guided/laser guided/radar guided/smart/fire and forget). Furthermore, the spear should have rocket propulsion in its shaft---- or perhaps the shaft can have a threaded end so it can be screwed into a specially designed disposable "launch shaft" (a spear shaft which ignites it's propellant after the user throws it) SO whaddya think? Is this a cool idea or what? Can this be done?
