I'm curious as to what the OP (and all the other folks who think Spydercos are ugly) view as a pretty knife? The Sebenza has been posted, but what else?
There's a lot to be said for tact. If you don't like the looks of something, there are far better ways of interjecting that into interesting conversation other than starting a thread called "Spyderco knives are really ugly".
Think about it - this post seems a bit inflammatory (even if followed by "Not trying to start a flamewar"):
Spyderco knives strike me as really ugly. That big ol' thumbhole making the blade look like the head of a duck or something. The blades look totally out of sync with their handles. And the handles, by and large, are ugly, too.
Most knives are seductively lovely. Not these babies.
I don't find Sebenzas particularly attractive (nor many of the benchmade alum/Ti handled models including the 710 - which I know is blaspheme, but that won't stop me from using any of those knives).
I use my knives, they're not for collection. If your knife is a talisman, then more power to you - you basically have jewelry. If you actually use your knives, then their beauty isn't the only thing that matters to you, so you have to understand some basic concept of form over function.
Spyderco knives were the first to allow opening with one hand - the Spyder hole is to thank for that and it stuck out of the top of the scales in order to allow for thumb purchase to enable one-handed opening. Nearly every manufacturer of production folders has adopted that round hole in one of their designs. There's a reason for that - it works.
As to their blades being "out of sync with their handles" - that really couldn't be further from the truth. Look at the Sage - much care has been taken to ensure that the contour of the blade-tang matches both the closed and opened scales. Many other manufacturers leave a chunk of unmatching blade-tang out when closed. That to me looks "out of sync".
Fit and finish on Spyderco knives is top-notch for a production folder. I've owned several more expensive knives that lacked that very thing. Edge/blade geometry are also taken into consideration for some of the "uglier" models too - they're cutters meant for specific tasks and they work well for what they were designed for.
If every knife looked the same, I think things would be pretty boring.
