The sizes are different, but these rulers have a lip that the rotary cutter "rides in." I have a couple of these True Cut rulers and love them because I feel there's less risk of the cutter sliding across the ruler and into my hand. I bought their rotary cutter too, but they seem to wear out. My NICAPA rotary cutter rides in the ruler track too.
