Whether the cartons or PVC and carpeting, -the thing cuts like a 1 and stays sharp longer. Then one turns with one touch the blade or replacing it with a new blade if both sides are set on edge. Replacement blades can be taken anywhere, tightly under control.
Even the cord-cutter is working fine, but only if the blade is actually locked when it is beautifully laid out, enters.
This avoids also for safety reasons, that you cut yourself, because you, the blade for cutting cord would surely not need to enter the sake of convenience.
The knife is great in the hand is very sharp and you can impress also properly determined without the blade bends or even breaks!
My Conclusion:
Especially when tool is the saying: "Whoever buys cheap, buys twice!"
Once bought this part and you have a reliable "friend" for a long time! :-)
