With a flat ruler you always balance on the seam when trying to align it. These rulers have a channel to hold the seam so you don't slip while cutting. In this set you will find the most common sizes of half square triangles. This is my second ruler set from Bloc-loc. I also have a few of these that you use to trim semi-rectangular blocks.
