Dixon Arkansas oilstone made in Germany.
In bottom half of a wooden box. Extremely fine feel, fells the same all the way around.
Box measures 4 1/4" by 1 3/4" deep and 5/8" high. Stone itself measures 3 1/2" by 1" and 1/2" high.
Box is beat up, but intact. Bottom of the stone has a chip on it. Feels like some remnant of a sticker or something on the bottom.
I haven't cleaned this or done anything to it, I don't know if the gray color can come off. Very flat, I can't see any dips from repetitive use.
