I have a pretty nice spyderco with partial serrations that I hate, is their anyway to chage it to all straight edge without making it look like shit?

I imagine that Spyderco can change it out for you...  give them a call.

A lot would depend upon the blade style. If anyone could do it with the highest probability of having a good turnout, it would be Spyderco themselves. Not saying others could not do a good job, just think the factory would be better prepared and equipped. Bear in mind it might well be at custom shop wages, if indeed they will do it. Ultimately though, it would be cheaper for the factory, to simply replace the blade, with the non-serrated choice, rather than paying the wages of their own smith...unless of course it is some limited production series steel. These are only my assumptions though. Either way though, it cannot hurt to give them a call or an email.

I'd be inclined to sell the knife with the partial serrations and buy a knife more to my liking.
