I know I said I LOVE my bloc-loc rulers, but I also LOVE my cutting gizmo. It's big & purple so you can't loose it on your sewing table, and for me, it really helps a lot. The thread cutter on my machine is in an awkward place and I tried using a seam ripper stuck in a spool, but I stabbed myself, which you can't do with the gizmo. You can also replace the blade. And it's very stable, so it doesn't rock or move when you use it. I love to chain piece!
