I’ve had a couple awful Apart hones. Barely bevel setters if I remember right, but small sample size and fits right in with swaty hones. They vary WILDLY. I compared slurry between three at one point. One was <micron(15-30k) One was about 5 micron (3-4K). One was 20+ micron (~1k)
Wow, that would explain some opinions.
A good john primble is nice in the way a good swaty is
I was not as impressed with the Primble I have. Marginally improved an 8k edge for me.
