Stone Tool Making Techniques: Pecking resharpening

Grinding stones were used to abrade edible seeds into meal.  With prolonged use, grinding stones often became worn smooth and lost their effectiveness.   The surfaces of these stones were sometimes resharpened by pecking to break-up the slick surface and re-establish the stone’s abrasive qualities.
