6" long, it actually has a fresh coat of hand rubbed Tru-oil on it, the dowel is how I hold it while I apply more finish. After I get enough finish on it I will screw a pencil into it just like every other gizmo out there.
That gizmo may be a broken arrow shaft screwed into the nut, all my gizmo holders have an arrow point taper on them so I can screw them into the 5/16" nut in the gizmo.
These curly maple gizmos have already been posted on the Trad Gang St Jude auction, I finished them about a week ago.
