Antlers are the best joint material imo.
They don't crack like ivory.
They hit great as evidenced by the popularity of Hagan and Zylr cues.
They do take a lot of work to prepare. Kinda dangerous too as you have to cut them on bandsaw really carefully.
There are several species of course. The ones I have, I'd rather keep private.
They are expensive already. Kinda disheartening too when you drill them and some show some diseases so they're only good for joint protectors.
Cutting and turning them round is a lot of work and some skill. Without cuemaker Kerry Zeiler teaching me how to cut them and turn them, I'll have no clue how to do it.
The marrow on them cannot be more 5/8 in diameter if you want to thread them.
To thread them requires good tooling.
Bill Hagan made excellent hitting cues. He used different species for collars, buttcaps and ferrules. To this day, Hagan Cues command top dollar.
Hagan cue were known for great hit and low deflection. I think Dick ran into one with a really heavy antler ferrule. If you use the tips of antlers as ferrules, you can leave them capped and thin enough to be light. They are very very strong.
They do come in different colors or shades. I'm happy with the ones I have b/c they are not too wild looking.
White-tail is prolly the most popular and the cheapest.
Their powder/dust btw is toxic. Very stinky too.
They take a lot of work to make imo hence the unpopularity. Much easier to use phenolic or ivory. Ivory commands more dollar too.
