Description: A middle-sized stone cutter. Transverse vertical symmetry of the working edge. The handhold is shaped anatomically for the right hand. There is a lateral groove for the thumb. The forefinger is stabilized behind the fore obliquity. The palm touches the back obliquity of the handhold part. The shaping enables perfect stability and firm grip when pressed by hand vertically and when the cut is lead horizontally even if the material was relatively solid (rough animal skin). Made of quartzrock.
