I would say the finich the on the Almite Walker, the only aluminum Spyderco I have daily carried, is slightly more durable than the mini-socom, which I also carried. I noticed more discoloration on the mini-socom which had less carry time the Walker. The kraton inserts help to make the mini-socom more slip resistant.
I am probably harder on these knives than most users because I don't like clips and I remove them. I prefer G-10 to aluminum as it resists wear better, feels warmer to the touch and is more slip resistant.
