Buy the one good knife. I can't speak for others, but at this point in my life, I don't need any more bottom rung cheap knives around. Can't get rid of 'em, I won't use 'em, so really no point to it.
After all, you don't want to be "that guy", right? I always get a kick out of it when I see some thread where someone is selling a high end midtech or even higher end production knife, and some genius intellect is in there like "Hey man, that's an awesome Shiro, I'll trade you this PM2 (in trash shape and base-model S30v), these two Mini-Grips (garbage shape AND half-serrated), this SAK (looks like it was dragged behind a car), and these three awesome Kershaws (I mean, it's three Kershaws. PASS.) for that Shiro! How bout it, broh!" and then watching the guy have to be nice to this dingus so others won't think he's a jerk. "Nah, I'll pass man, thanks for your kind offer!" LOL
