Maybe to keep the precision woodworkers happy?
I have rules with both types of graduations but find myself using the fractional rules the majority of the time. (For imperial stuff of course.) Just too accustomed to working with bolt sizes, drill bits etc., in fractional sizes I guess. There have been a number of times where I have tried to measure something close to the chuck jaws in the lathe, or down inside a bore and even a little 6 inch pocket rule would get in the way. Now that I finally have a small set I'll probably never ever have a need for them again.
