noun
clipper
KLIP-er/ˈklɪpər/
A tool or device for cutting or trimming.
The nail clipper has a raised lever and curved cutting jaws.

Etymology
Clippen plus -er first named someone who cuts, such as a sheep-shearer or barber. In the tool sense, the same formation names the implement that performs the cutting.
In context
we've cut the skin area using just a closed clipper, which, again, is very close, but you're gonna see a much more noticeable amount of stubble left in place.
