I have left handed scissor, left handed pinkers, and use them right handed. Yeah, I know, makes no sense. I just can't use them left handed. So I never waste money buying stuff made for lefties. I do just about everything except eat and write with my right hand, except use this rotary cutter.
I will try to find some of the sandpaper dots for the ruler. I have a 17 inch long clear one, the longest I saw in the store. I tried using the cutter after reversing the blade, and it makes a world of difference.
