This is a knife or cutter for modeling use.

For those that like to leave a little bit of nub on the part (to be cleaned after) these nippers may just be what you are looking for! The Nokoru Nipper by Mineshima is not a flush cut pair of nippers and instead leaves a little bit of nub from the plastic runner on the part. These nubs can then be cleaned off by filling, sanding or cutting the reamaining nub off the part with a design knife, however the user prefers!
