I use the 1/4" end for measuring, for holding fabric in place (like a stiletto without the sharp point), for turning fabric when 2 pieces are stitched together, to remove freezer paper from applique, to help push things in place while appliqueing or just plain sewing, and to help make square miters. Those are the things that immediately jump to mind. I'm sure I've used it for other things, but think I need more coffee to really kick start my brain!
