I see knives similar to the way I view women...
("Viewed" women, because the one I'm currently with is the only one I view anymore)...
I really don't have a "type", I know what I like, and I know what I don't like, but there's no real rhyme or reason, or specific definable "eureka" moment to some it all up...
Old ones that are not completely worn out and decrepit, young ones (as long as they're legal), big ones, small ones, thin ones, chunky ones, red, brown, blue, green, natural or synthetic, European - African - Latin - Asian, there is no specific turn off, or turn on for that matter for me...
I know I can look at one and say, "I love it!"
Or, "ew, not for me."
Or, "hmmmm, intriguing."
Or, "well, I don't hate it."
But I'm not always sure what "it," is exactly that catches my eye, it just does, or it doesn't... It could be too flashy, it could be too plain, It could be the stag that makes it pop, or it could be the stag that turns me off

I can say Gerber lost my respect, (blatently cheap companies like MTech and Tak-Force never earned it), I find the vast majority of Spyderco to be an aethetic eyesore, QTRM5TR knives are an even bigger eyesore (and the name spelled like a preteen girl's text message makes it exponentially worse), I'm not a huge fan of serrations, and require my knife steel to be identified with at least 0.5% carbon (Bos 420hc and Trusharp being the exceptions at just a hair under).
That all said, blatently cheap brands aside, QTRM5TR would probably take the cake...
I would probably buy a fully serrated, "surgical steel" Gerber, that had a typical Spyderco profile, and was reported to have been made with 3cr13, at a flea market, before I spent my money on anything with QTRM5TR written on it... She's just an ugly chick with a horrible sense of style, and a crappy personality to boot.
