This simple rolling jig holds screwdrivers at a constant angle to the sharpening stone. Simply squeeze the spring loaded opening to insert screw driver and adjust to desired angle. Roll across stone to hone one side then flip the jig over to sharpen perfectly parallel sides. Makes the task so simple you won't have to put off dressing all those damaged blades you've been meaning to get to. A quick dressing before each job makes things go smoother. Like your watchmaking school teacher told you.
