The orange bit in the picture is actually a stop that allows you to set strip length. The stripping jaws are comprised of teeth set into flexible backings. You can preload the flexible backing with a slide on the top of the tool, that’s what adjusts for different wire gauges.
The preload adjustment is my only complaint - it’s difficult to change the setting with any kind of precision and you often have to do some trial and error to get everything just right.
But once it’s set it’s really repeatable. Makes stripping and crimping signal wires a breeze.
