wire saw

A wire saw is a cutting tool that uses a thin wire or cable—often coated with abrasive material like diamond particles—instead of a toothed blade.

Wire saws cut through materials that would damage conventional saws: stone, concrete, bone, or metal.

In surgery, a wire saw can cut through bone in tight spaces.

Larger industrial wire saws slice through marble quarry blocks.

The thin cutting edge minimizes material loss and allows curved cuts impossible with rigid blades.
