Hmmm... my Martelli mat just arrived. I’m concerned about the slipping issues mentioned here. I have already sliced my ruler holding fingers cross ways with a slippery mat. I have the cutter, and the round mat. Here are some of my experiences with Martelli products as mentioned in this feed-
* Yes, my round mat does scratch with cutting.
* the cutter really is easier on the wrist for me, but it collects lint in the blade casing, and I can not figure out how to completely clean it out, therefore I find the blade starts sticking rather quickly. When replacing the blade, I’ve needed help sliding the blade into the casing. (I’m Actually very good at mechanics)
