I think there are some blocks where you need to stop a 1/4 inch from
the end, and the clear 1/4 foot has a red mark to tell you when to
stop. I have never used it for that though. I do think it would be
handy on the corner of binding, where you stop and then turn, however
once you do a couple dozen you can do them in your sleep. If someone
were a perfectionist (I am NOT) then it might be handy for that as
well.
