Pechauer Black Ice  5/16 x 14 Thread 13mm Break Shaft for Pechauer. Pechauer  With our Infused Chemical Engineering (ICE) Technology, chemicals are infused into the cells of the wood, changing its structure for added density and a smooth, glass-like feel for less friction and increased velocity. This multi-step process is not a barrier, but a permanent treatment that penetrates the entire shaft.

Average shaft weight of 6.4 oz for a weight-forward balance delivery. This means more power with less effort for a maximum break (helps make any cue a break cue).
