Love this tool!

The great big handle for the larger quilt rules seems too awkward for me, so I never bought one.
However, when I saw this one for the smaller rulers, I decided to try it.
I use small square rules often, both metric and inch, and use my 6 1/2 inch by 12 inch ruler just as often.
This handle can be used for all of them and makes it much easier to move them around.
And, by the way, I use the non-skid plastic on all of my Omnigrid rulers, and it really helps.
