Spyderco does NOT sell just the base for the Sharpmaker. I wanted to buy the diamond and ultra-fine stones and a spare base to store them said:
I have a very old Sharpmaker, with only one angle and it still does a good job. Trying to get just a new base, with more angles, met with a brick wall. Guy in the service dept. was rather snarky when he told me that they sell Sharpmakers....not parts. Then he, apparently, thought about it and relented.....asked for my address. I thought he might have changed his mind but I never heard from him again. Whatever.
Most good companies will try to be of assistance in a situation like that....you know, serve their older customers when something needs replacing or fixing.....who bought their products long before they were so well known.
Considering Spyderco's rep (including the owner) I was both surprised and disappointed that this service dept. guy seemed to think I had some sort of personal problem. Had I been able to get the newer base I was considering buying the diamond stones for reprofiling. Rather than spring for a new Apex. Oh well.
