I have two of these -- one has 1/2 inch slots, the other has 1/4. I think they are June taylor, I don't use them for cutting long strips, but I do use them for cutting those strips into sub pieces. I recently did a baby quilt and needed a lot of 1.5 x 2.5 and 1.5 x 2.0 and 1.5 x 1.5, so I cut WOF by 1.5 strips just with my ruler, then used the slotted tool to cut the smaller pieces. Speeds up the process quite a bit.
I have an accuquilt, but the only strip die I have is 2.5. Just can't bring myself to pay for additional dies!
