Sorry I wasn't clear - the ends of the teeth will be different lengths unless you're better at hand grinding than I am. With the endmill in the mill, the scraps of paper go between each corner (the corners that were dull) and the machine table. Tug on each one to see which one is long. Use a stone to adjust its length until they are all the same, with the endmill still mounted in the mill. It doesn't take much, you're just dealing with the corner of the endmill. A stone can take off quite a few thou with just a few licks, just keep in mind the geometry (clearance, mostly). You can use an indicator too. It affects the finish - one long flute will leave a deep swirly.
