Although I had read in a review that the rotary cutter was delivered blunt, I still decided to do it. I was very disappointed! The blade is so dull that it does not even cut paper. I find it very unfortunate that just the blade - that's probably the most expensive components of this material - High is very bad. Unfortunately, I've tried too late after buying the rotary cutter and the packaging had been disposed of. Otherwise I would have complained about it immediately.
In itself, I can recommend the rotary cutter, as it is very convenient to use, but definitely not this. For a rotary cutter without sharp blade is not usable.
