Okay, strictly looks, and well known production folders. Let's not even consider functionality.
OVERALL: This is going to be an upset but the winner is the CRKT Howard Viele Wasp. I don't even own one, nor want one, but I think it's a knock out. IMO, The Limited Edition carbon fiber version made in Switzerland is even nicer and should be in the Museum of Modern Art.
Runners up:
Above $200 - The Microtech Kestrel - so cool looking, it's almost sick!
Between $100 to $200 - That Benchmade 920 that Mental Patient posted. It's beyond beautiful, it's sublime. It's the Heidi Klum of production folders. I'd also say the Benchmade Ares is mighty "purdy".
Under $100 - The CRKT Brian Tighe Tighe Tac. Classy like an Armani suit, but less than $50!
AND "BEAUTY IS IN THE EYE OF THE BEHOLDER" AWARD:
The stainless steel handled, all serrated, Spyderco Police. "What the f...?", is what you're probably thinking.
If you want a menacing looking knife, if you want a knife that goes good with (as I said at the Spyderco thread) a '69 Camaro, and a raunchy girlfriend who looks a little like Madchen Amick riding shotgun. Think how cool that tapered stainless steel handle would look sticking up from the back pocket of your Levis.
The SS serrated Police looks like a psychotic barracuda with an attitude problem looking to eat some guppies. It exudes that same nasty vibes you get from a pearl handled, straight edged razor tucked inside a boot!
