Coticules will last so long as you don't drop them typical wear aside. Some synth waterstones warp or craze over time, others not so much.
We need pics!Just got a Coti in the mail with a name & date scratched in the side June 1906, even after lapping I think this stone will outlast me!
Synths ????
One could argue that the crafts person that is wearing out their stones is actually the one who is getting the better value.If you never get into hand tool woodworking stones last long enough that you’ll never bother calculating out the cost per hone or year. If you get too deep into hand tool woodworking though you’ll wear out DMTs, Suehiros, and eventually softer JNATs.
