I use this at work and there is nothing like it on the market for mass production of electrical equipment that requires wire stripping. Nobody else makes a wire stripper that you can place on a table and strip dozens of wires one after the other without getting more than a bit sore in the wrist. You can also use it whether you are left-handed as I am, or right-handed, it just requires turning the tool around in the holder to face your favored direction. The part I like the best is that the holder allows placing on the table in a stationary position for continued use. I don't see anyone else making a stripper that is designed to make mass stripping easy. I often have to make hundreds of lead wires at a time and this is my preferred tool. It's worth paying for and lasts for years under heavy use.
