Seems every collector has a few clunkers. I'm no different!
When I was younger and poorer and didn't know any better, I'd pick up a cheapie just because I liked how it looked. Even know, I'll sometimes pick up a knife just for it's exotic look. Just off the top of my head: a tiny little Spanish Joker liner lock with horn scales and 1" blade; a Pakistani "pappoose" Bowie set (10" blade + 4" blade, in one sheath) that are built like tanks, and actually take a mean edge; a Darrel Ralph-clone folder with scales made of circuit board (appealed to the geek in me, I suppose); a very long, very thin Spanish Andujar "stylet" in brass and horn, that I use as my letter opener; a Pakistani Randall #1 clone, that also takes a mighty nice edge (for 5 minutes, anyway!); one of those Blackie Collins non-metallic assisted opener tacticals, just because the Dept. of Homeland Insecurity will probably ban them soon; a trio of gaudy-as-Hell Arab knives my grandfather brought back from Beirut (he worked there before it turned into an urban warzone); and a smattering of cheapie autos i bought just to study the mechanisms.
For all the crap I ya about Paki knives, I must've been lucky, because most of the ones I have are shaving sharp, even if they don't hold it well. Fit and finish are crude, true, but they're solid as all get-out, with big ol' beefy slabs of 440 for blades. (Of course, any that I bought that didn't meet those criteria were traded away, too...)
Besides, I think crap knives serve an important purpose: the teach us to appreciate the GOOD knives more!
