Here is some unbiased opinions
Sebenzas have great fit and finish, my Spyderco southard and Tuff have been almost as good, My Chaparral and PPT, not as good. The tuff and southard have the best fit and finish I have seen in a full production knife.. The sebenza I have is off center to the left, but the fit and finish is marginally better than spyderco. People like to say hinderer fit and finish as as good as a Sebenza. I would put a hinderers fit and finish about where Spyderco Taiwan knives are, maybe a bit lower. The fit and finish is pretty much the same as my Strider SMF (new one in PD1) . The fit and finish differences between these knives is barely noticeable, yet people seem to think that its a huge difference. Handle my spyderco tuff and my sebenza and tell me what makes the tolerances better than my tuff, with out quoting chris reeves 0.001 inch accuracy. Cause the finished product is nearly identical in fit and finish.
