That's right Ed, when honing with water, the surface     oxidation of the
microscopic iron shavings lightens them enough to ^LIFT^ the swarf off the stone
and right up to the surface of the water.  I think.

nice stone, dude.  yr pl gam




 It is 2" X 8”.  The Berea oil stone I showed a couple of days ago says “for use
with oil or water”.  I have never used water on a stone.  What happens?  IS
there too much swarf for oil to get rid of??
