A few months back, I bought a set of Spyderco ceramic stones from
Highland Hardware. The first few times I used them, I was
unimpressed. The instructions said to use them dry. I checked
Google, and found others complaining that they load up very quickly.
I found that the fine stone loaded up so quickly, that I was just
burnishing the metal by rubbing it against the metal loaded into the
stone. The ultrafine stone usually ended up dulling the edge by this
same effect. So I plodded along by honing one bevel, then scrubbing
the stones before reusing. They were useless for lapping backs.
This got old quick, so in frustration, I flooded the stones with
water, and lo and behold, they cut very well, and the suface tension
of the water floated all the metal away. I was able to work at an
acceptable rate by keeping the stones VERY wet.
Most other Google posts were complaints about the stones not being
flat. No issue here, they are all flat. Anybody else using these for
p.s. the medium grit can survive a
3 foot drop onto a tile floor. DAMHIKT.
