Manufacturer: Keith Andy Product Name: Black Jack Jump Cue Butt Material: Orange Stained Maple Ferrule, Tip: Integrated Ferrule Diameter: Approximately 13.9mm Butt Length: Approximately 34.9mm (excluding joint, including bumper) Shaft Length: Approximately 71.5mm (excluding joint, including ferrule) Accessories: Dedicated Joint Protector Condition: Neither the butt nor the shaft has any noticeable warpage. Other: The butt and shaft have been cleaned before listing. It has been used and stored carefully. There are some minor dents due to normal use, but the condition is good. It was purchased as a limited edition item at the time of purchase. For this reason, it is a rare item with the Black Jack logo engraved only on the bumper. It may be a prototype. ＜Manufacturer's Description＞ With a 13.9mm ferrule diameter, a thick taper, and an integrated tip and ferrule, it is possible to jump the cue ball with about 70% of the usual force. Therefore, there is almost no chance of the cue ball going out of play, even for long jumps or shots along the rail. Also, because the cue ball does not bounce as much, the control is good, and it is much easier to pocket the object ball compared to a regular jump cue. As a result of having over 500 people try the prototype at an exhibition, almost everyone gave it a favorable rating.
