Looks similar to a "Wouff-Hong", which is used to enforce law and order in amateur radio operation.
Rolls like a 2x6.how does it roll on the table??? is it straight?
Seriously??? You guys don't know what this is? Its a combination standard length cue/short cue, you know, for when there are obstructions around the table or a wall that is too close. You use the long standard handle when there are no obstructions, when the standard handle is too long due to an obstruction you use the short handle, problem solved. IE: you are shooting and the cue ball stops frozen to the rail, you quickly discover that your cue is too long, it hits the wall, you have no back stroke whatsoever, even jacked up, but wait, its also a short cue, viola, problem solved!!!! All with one handy cue, no reason to carry 2 cues or search around for that stubby cue when you need it.
