Stone has been used to make a wide variety of tools throughout history, including arrowheads, spearheads, hand axes, and querns.

A normal pickaxe handle is made of ash or hickory wood and is about 3 ft (91 cm) and weighs about 2.5 lb (1.1 kg). British Army pickaxe handles must, by regulation, be exactly 3 ft (91 cm) long, for use in measuring in the field. [citation needed] New variant designs are: With a plastic casing on the thick end. Made of carbon fibre [citation ...
A mattock (/ ˈ m æ t ə k /) is a hand tool used for digging, prying, and chopping. Similar to the pickaxe, it has a long handle and a stout head which combines either a vertical axe blade with a horizontal adze (cutter mattock), or a pick and an adze (pick mattock).

Dimension stone rates very well in terms of the criteria on the ASTM checklist for sustainability of building products: there are no toxic materials used in its processing, there are no direct greenhouse gas emissions during processing, the dust created is controlled, the water used is almost completely recycled (per OSHA/MSHA regulation), and ...
