just about finished with this one.it is only the second j/b i've made.it is slightly curly Purplehart with Macassar jump handle and a Purpleheart shaft.the tip/ferrule is a material similar to G-10 but harder and it doesn't amke the terrible noise G-10 does.rings are SW style ivory and the pins are both 3/8-10 aluminum with the jump pin having only 3-4 threads or so for a quick disconnect.the cue is sold.
