Slice’s material, zirconium oxide, is significantly tougher than metal and wears down much more slowly. This means that it does not necessitate a risky initial sharpness.

Define the term, “Cutter”.

A cutter is a hardcore metal device that is used to carve, form, and eliminate material from a workpiece using machining and abrasive tools.

Distinguish between cutting and machining.

The cutting tool compresses a small layer of material on the workpiece in order to shear it away, while the machine tool holds the chopping toolbar.

Will these be able to punch hard plastic wrapping?

No. It only just managed to tear via strong tapes.
