These are upgraded wire strippers out of the multi-sized wire strippers. This include: 20-30 AWG strippers, wire cutters, 'plier' tips, and a wire loop. Ground blades for precision cutting. Spring return, comfy molded handles and a closing-lock.
Great for general usage, we use them for standard 22 AWG solid-core breadboarding wire and 26 AWG stranded ribbon cable, sometimes for other thin wires like thicker wire wrap. They sometimes don't work so well for 30 AWG - that's the trade off with the basic tools. If you need precision, high repeatability and extra comfortable rubber grips check out our professional wire strippers from Hakko
