AXE GRINDING STONE
The prominent feature on this side is a large worn
concave grinding surface area that measures 11 inches
(7.9cm) long, 8 1/2 inches (21.5cm) wide and 5/8 inches
(1.5cm) deep. Since axes were also smoothed or polished
on their sides it's possible that this side was used for
that purpose. There are also at least 12 small holes on this
side that may have been used for cracking nuts.
