Yes. Stones are excellent for creating or adjusting crisp grind lines.


Bill,
Do the Japanese waterstones break down quickly? Which is more desirable, hard stones that hold their shape longer or stones that break down quickly and loose their flatness but expose more fresh sharp grit?
 
Also, stones are recommended to be used with a honing oil. Do you guys use the oil suggested by the stones seller or something else? Can I use 3in1 oil or WD40?

I was using windex. I’ll look into this myself.
 
The cheap waterstones do break down quickly, and conform to the shape you are abrading. You do have to adjust them periodically to keep lines straight, because they keep wearing down. I get the cheap ones from Lee Valley.
 
I have mostly used Windex with mine as well, which works nicely, and will probably try out kerosene too. I've been meaning to pick up some of this "Polishing Lubricant/Diamond Thinner" solution that Falcon Tool sell to try out, which I've heard recommended by another maker. Maybe it's better, maybe it's not, but I'm cool with getting a pint for $5 to give it a try myself.

They'll removes any scratches if you use the right grit. Due to the finish that the stones themselves leave not being very uniform or clean looking, I think they're best for going up ("up" in grit number, or "down" in grit size if that's your preferred nomenclature) through the grits and then switching to paper for the final grit and finishing passes. J-hooks are mostly caused by technique, so they can also happen on the final grit and finishing passes.

This is what I use to great success, I think I might start soaking my stones in it or the stoning oil that I purchased from falcon. I don’t know what would be better.
