The official definition of the grit levels of sandpaper goes something like this:
40-60 coarse 80-120 medium 280-320 extra fine 360-600 super fineThe highest number I've found is the 600.
But in several references to waterstones I've seen the numbers 1000 and higher, maybe even
3000. If this is on the same scale as above, it would imply that the waterstones are much finer than "super fine". Can this be right?My question is: Is the same grit scale applied to waterstones and sandpaper or do waterstones have their own scale?
The reason I'm asking is because I'm considering trying to sharpen my tools with sandpaper (the Scary Sharp method).
