I'm doing some heavy reprofiling on a knife, just curious if anyone has a solution to this that I'm not aware of. I figure with grinding off as much metal as I am, this is to be expected, but I figured I'd ask anyway.
This is a 80 grit Moldmaster, clogged up with 1095.
I use Windex on it and try to keep it wet, but the slurry always dries and clogs. I rinse/scrub with a toothbrush and frequently lap them on a diamond plate when doing heavy work like this, which helps but it doesn't take long to get back to this point, and it's often worse than this. On higher grit stones, they seem to almost glaze over and stop cutting unless I lap them.
