Works well and much safer than a utility knife or boxcutter
Seems good. Cuts through cardboard in a sawing action surprisingly quickly. Much safer than a utility knife for most tasks. Depending on the nature of the cardboard, the cuts can somtimes be hard to control and the result is a bit rough. So there are still jobs that are better done with a sharp knife on a cutting mat. But for big cuts and box demolition, it works very well. The 'fluorine' apparently refers to a PTFE coating. Doesn't seem to blunt quickly like a knife blade, but time will tell.
