Cap on top would be cool!
Like another reviewer said cap on top so I could store my acorn nut driver in handle would be sweet.
I am not a huge fan of the set screw but it works.
I needed this for the acorn driver because I figured using the hands is safer than a cordless screw driver/drill. Get the torque just right by hand.
