The stone knives, arrowheads, celts, hoe-blades, hammers, nails, awls, etc., associated with this pottery are of kinds which though simple and often crude in type are nevertheless not early, but date from the transition period to the age of metal and the earliest centuries of the latter period.

In the surface of the metal the workman cuts grooves wider at the base than at the top, and then hammers into them gold or silver wire.
The metal is then heated, not to redness, but sufficiently to develop a certain degree of softness, and the workman, taking a very thin sheet of gold (or silver), hammers portions of it into the salient points of the design.
In Mexico, Colombia and Peru the cutting of friable stone with tough volcanic hammers and chisels, as well as rude metallurgy, obtained, but the evidences of smelting are not convincing.
For building purposes stones were got out, dressed, carved and sculptured with stone hammers and chisels made of hard and tenacious rock.
Minting by means of a falling weight (monkey press) intervened between the hand hammers and the screw press in many places.

Copper was known to them, and it is possible that they knew how to make cutting instruments from it, but they generally used stone axes, hammers and picks, and their most dangerous weapon was a war-club into which chips of volcanic glass were set.
Because of these facts the great hammers have given place to enormous forging presses, the 125-ton Bethlehem hammer, for instance, to a 14,000-ton hydraulic press, moved by water under a pressure of FIG.

Probably it was thus highly finished by beating between polished stone hammers which were almost flat on the face.
The design was then beaten into relief from the back with hammers and punches, the pitch bed yielding to the protuberances which were thus formed, and serving to prevent the punch from breaking the metal into holes.
Nearly Ioo stone implements were excavated - axes, hammer axes, stone hammers and mauls - which, according to Dr Gowland, who superintended the work, had been used not only for breaking the rude blocks into regular forms, but also for working down their faces to a level or curved surface.
