The glass 500 should be plenty fast for stuff like wusthof/vnox, even with a couple chips.
I have a SG 500, and it’s a nice stone. I’d only start with it if the knife was in really good condition, though, and was already semi sharp.+1 on the Shapton 500 glass (get the double thick version).
amen. maybe the real solution is to stop sharpening crap knives until I live in a situation where a belt sander is possible.slowly dawning realization I should not hurt myself using a stone where a power tool made more sense
