The insulating sheath of the electric wires can be cut and removed with a wire stripper. However, the pliers should not touch the core and should provide the ability to remove the cut piece of tubing. There are several solutions and models of grippers.
More technical information on this page in the dutch version.
The wire stripper is sometimes combined with combination pliers.
