Full of anticipation going down and then the first blade was a very short time over (about 20 minutes cut and the next and the next, ...). Cutting fine ornaments from Overheadfolie on cutting mat. So really there is no reason why the blade at the top break within a short time. And then they are no longer usable. This is the first time that I write something for an article! But such a poor quality is rarely encountered me. I hope the other scalpels, which I will try now are better!
