Just realized, what if Sanda didn't put the whetstone in any water and just sharpened it raw 😭
Well, lubricants only carry removed steel (and for some relatively modern stones spent abrasive) off of the stone’s face. Without enough water or oil, retained metal fragments in the face of the stone clog up the abrasive on the stone’s face, but not entirely, and what’s showing will still abrade metal. Enough force will even shear off layers of the stone, also ripping off the retained metal in the process.
In reality it can be beneficial when sharpening a tool to work with less lubrication and let the stone load up a little bit to control speed and degree of polish. Particularly relevant with some Japanese natural stones.
3/10 sharpening scene. Insufficient lubricant. Impossible angle control considering the force being used. Poor stone maintenance habits. And no utility in getting that degree of polish over the surface of the entire blade; what kind of self respecting mythological cryptid human hybrid tween hasn’t heard of a microbevel?
