About 6.50 mins in, this guy says slurry does the sharpening & not the stone,and he's on a synth. T or F ?

Certainly. Is your slurry an abrasive or a filler to lessen the abrasive qualities of the stone?

An abrasive slurry on top of a stone is certainly going to be more abrasive than a partially buried particle of the same grit.

I feel in this video he could simply go to a courser stone and accomplish the same thing without slurry.
