One of the things a person must master in the journey of becoming a cue maker is learning how to use anything. When challenged with a tricky material, you have to choose what kind of cuemaker you are going to be. Are you going to refuse to use it because you aren't comfortable for whatever reason? Or are you going to invest the time & work in learning how to utilize that material and overcome your discomforts? With this quest comes experience and wisdom of knowing how to pick your battles.
Lignum vitae.
Good for nunchuks but not for cues .
FUGLY and I pity the cutter.
I have read from multiple sources that the USN uses lignum as shaft bearing in nuclear submarines because it is naturally lubricated, stable, and ultra quiet compared to oiled metal. That has nothing to do with cues but I thought it was neat.
