edge saw

As a result a whole series of new inventions were designed to "clear the saw" such as edging saws, butting saws, and rollers for shoving away the boards.

Edging Saws, Dado Heads and Cutters Made of electric furnace steel, correctly tempered, smithed, and hammered for perfect balance, trueness, and easy cutting.

Much of the machinery will be familiar in any engineering shop anywhere, but the specialist equipment generally uses diamond edged saw blades and edging wheels to work crystal and glasses delicately.

The very accuracy of the way in which the stones have been cut has led specialists to speculate as to whether they actually had laser-cutting devices or at the very least diamond edged saws.
