Thread: Flea Market Whetstone

the color on mine & photo # 3 was manipulated to help bring out the texture on the inside of the stones.
I don't rely on color that much, especially when different cameras & conditions are present.
Stones in person, often look different in photos. I also see the different dark pigments in all the photos to indicate possible oil/lubricants used at the time of manufacture. I believe the difference in photo # 3 is that the stone is extremely dried out & "crumbling" ,,IMO.. I look at the old Nortons, Carborundums on Ebay daily,,,& I see this condition from time to time.
But who knows without examining the real thing & not a photo.
