|I've always wanted a professional paper cutter, but the cost was just too much for a "good one", plus they take up too much room. These are great for cropping photos, crafts, etc...anytime you want a perfectly straight and/or square cut on paper.
I used one of my % off coupons at Joann's to purchase a second rotary cutter, one the same size as my first. I wrote "Paper" on both sides of the older handle with a magic marker, so the 2 cutters can't get mixed up.
The beauty of this is, paper doesn't need a blade as sharp and perfect as fabric, so you can use the old fabric blades that you'd normally discard. I love that I get to recycle the old blades.
I think using the gridded ruler and gridded mat for paper cutting might actually be easier and better than using a professional paper cutter...and it doesn't take up any valuable space in your house.
