Ordered the replacement set and when they arrived everyone was broken making them un- useable.
Ruixin Whetstones Replacement Set 4pc with base
The stones are just too soft to cut metal. They shave off into dust. My coarse stone is already dished out from wear. Had them less than 2 months. I like the idea of the system, just not happy with the stones. I'm currently ordering another set of stones just to keep operating and because I like the system. I'm going to include diamond stones in my order just to see if they work better.
