Enough hypothetical maiming of the wildlife! I would be interested to hear what knives (in steel or other suitable metal only please), would you build if you had all the skills and all the opportunity. I am thinking that perhaps for three categories of tool: a) Fixed blade KNIFE of any size under 18 inches blade length NO SWORDS PLEASE, b) folder under 4 or 5 inch blade, c) multitool, what materials and design features would you use without regard to patent or copyright? Ask yourself what is most important: the potential uses of the knife? the steel or other material? tempering? blade shape? length? what kind of grind? Full guards? Type of handle? What type of lock? Would it be an automatic? What tools would you most want on a multitool were you limited to ten or twelve? BE REALISTIC if you can find it within yourself. It might be useful to assume that you only had the budget to make yourself one of each type of knife so there could be no backtracking and it had better be versatile if you are or narrow if you only want it to by the Ninja Rambomonger. What would your knives wind up being? Or has everything already been invented or discovered for this age old class of tools? Hopefully we'll draw some interesting responses that don't involve any of the Earth's lifeforms other than a bunch of wannabe bladesmiths. Who knows? Someone who could make your knife might read a good set of design features and give you credit for putting the ideas together. Think of the Spyderco Mariner which I heard was the first production knife with a hole in the folding serrated blade with a pocket clip all in the same package.
