And I must say, just great! The knife can be super easy and quick to settle the coat. It is also not in danger too deep to cut and damage the insulation of the individual wires. At times it has everything in one tool with this knife. While I use further my "automatic" stripper, but if you just do not have the on hand, you can also easily remove the insulation of the individual wires with this diameter.
Conclusion: Whether professional or amateur, if you're dealing with the electrical installation, you should buy this knife. It simplifies the work a lot easier and it is even faster.
Price / performance is for my being Top!
