Machine knives, also called industrial knives, are tools which are mechanically guided and driven, and which work with a chipless or cutting action. They cut countless everyday products in industrial manufacturing.

Circular knives, also called round knives, are characterised by their small gauge and their mostly circular shape with corresponding diameter Ø, and by their cutting geometries with either a flat, slotted or toothed cutting edge. The cutting motion is mostly rotating or stationary. The diversity of these knives is very great and varied. They are used in all sectors of cutting, shredding, scraping, punching, sectioning, perforating, severing, skimming and finishing.
