Name one company that releases a pile of new stuff every year, not only that but a huge variety of interesting stuff?(
Kai(Kershaw/ZT), Condor, Spyderco(I'm not as fanatical about their designs as some people but they got a lot of fans)...was that question supposed to be rhetorical? I know there's a lot more stuff I'll be picking up from Kai and Condor this year than I will from Cold Steel, and even Spyderco has about as many things as I'd like to get, they are just more than I am willing to pay($200 for the Karahawk...don't see that happening, even though I'd certainly like to have it). Ka-bar only has a few designs coming out this year, and even from those handful there's 3 of them I plan on getting, which is at least currently the same number of things I plan on picking up from CS(though if CS announces those machetes that BladeHQ lists as due out they will likely pass Ka-bar).
Now back to the point, we like folders because we USE folders. I can carry a different folder every day of the week, but no matter what folder I carry on a given day, I will use it. Machetes and big knives can be used for hiking, camping, and yard work. Even spears are sometimes used for hunting. However, we aren't samurais, we aren't knights, we don't spend the day hunting vampires or zombies, so...the ONLY time we will use a sword, or poleaxe, or warhammer is when we goof around slicing up fruit or water jugs out in the yard. Don't get me wrong, that can be fun, and there's nothing wrong with owning swords and poleaxes or whatnot, but in terms of usefulness, they just...aren't that high on the list, and a lot of people just aren't interested in spending $200 or whatnot on something that has literally no practical use. Even a lot of the people who are willing to pay for it aren't real likely to buy several of them, whereas a lot of folder guys will pick up several different ones.
