Good looking cue! Odd screw for Rick, isn't it?
Rick's standard pin for playing cue's is 3/8 x 11 but he uses the 5/16 x 18 in both section's of his jump break cues. Like most cuemakers he will use what ever the customer requests so maybe that was the option with this cue. His small pin cues play great and lots of people use the jump breaks as their playing cue.
