DOWELL 22-30 AWG Wire Stripper Wire Stripping Tool Wire Cutter And Multi-Function Hand Tool，Professional Handle Design And Refined Craftsmanship.

For the wire exposing, I really recommend just investing in a pair of wire strippers. These cost $7 and the 22-30 size will probably cover any size wire that you have in a kit. (I owned a pair of regular wire strippers but they didn’t work on wires as small as the Rolife kits use.) Then it is literally a case of sticking the wire into each successive hole until you find the right size and the coating will come right off with a gentle tug.
