It is a tool mounted in a lathe that has two wheels that cut/press the knurl profile on the object.

A knurling tool actually cuts the pattern. The cutting wheels are very hard and have sharp teeth. On a crosscut pattern (what you usually see on grips and pegs) one wheel has teeth angled one direction and the second wheel has teeth angled the opposite direction. The wheels are pressed into metal turning in a lathe and a fine feed is used to move the tool across the side of the part being knurled. As the wheels turn, they take out small slivers of metal (chips). The tool is kept in contact with the material and passes back and forth accross the part until the teeth on the knurling tool have cut away enough metal (deep enough) to acheive the desired pattern. Different patterns require different wheels.
