I have SP 1K and 2K so the 1.5K grit is really not being used a lot. Only used the back side and still have 15.5 mm thickness after cleaning and flattening. It’s a very fast stone and produces a toothy yet refined edge for kitchen use.
The Atoma 140 and 400 are still in good shape. Used them for stone flattening mostly. Used for thinning once just to try it. Didn’t like the sawing feeling so never did it again. Should still be able to flatten your stones for many years. I got new ones with handle attached after I decided I will never use them for thinning so no longer need these 2.
All 3 combined $100 shipped CONUS.
