Wire Stripper - SW Stahl
This combination tool allows you to cut and strip insulated wire with ease and also crimp common insulated connectors. It is a nicely engineered, professional quality tool.
The tool adjusts itself automatically to the wire diameter (gauge) and it works on wires from 0.2 to 6.0 mm2 (24 - 10 AWG).
An added feature of this tool is the ability to strip away insulation in the middle of a wire. This is very handy for joining two wires together without the need to snip the end off of the existing wire.
See the video for a demonstration of how it works.
