KNIPEX 12 21 180 precision stripper with metric blade positions
Compound stripper with clamping jaws and replaceable indexed blades

Check the fit
Compare the actual marked cross-section with the blade positions. Use the metric table when your wire is specified in mm², since a nominal AWG conversion can obscure which position applies.
When to choose it
The 12 21 180 uses defined metric blade positions and a clamping jaw that holds the conductor during the strip. Its length stop is helpful for repeating a connector-specific setting across leads of the same construction.
