remix of another shaping tool, made the handle a bit bigger with textured finish to eliminate the slot to tighten the butt and gives a bit more to hold onto, added a stencil to trace when cutting out sand paper, added a cutout of text of the sand paper size to be cut out if you lose the stencil or forget the size, it's hidden once sandpaper is added and revealed when removed as i always forget these kind of details.
