I been working with snakewood for over 10 years and have only lost one piece in that time. It was my fault not the woods. You have to treat it like ivory +10. It does not like low humidity, heat(direct sunlight) and rapid temp changes at any stage from raw wood to finished product. Do not try to treat it or impregnate it with any thing and stay away from any that is being sold as such. I have several rounds with a core hole punched through them, solid rounds hanging and squares at various stages of dewaxing. Once they are dewaxed they are left raw until they get the sealer put on them after their final cut. But........my shop also stays at a consistent humidity range 364. I've used it from full length beauties to points and sleeves and everything in between.
My wood is happy and to date have not had any cracked snake cues come back. (hope I didn't just jinx myself)...knock..knock.
BUT.....all that said, it's hard to guarantee this wood in a cue after it leaves my shop because the wood may be more susceptible to customer mishandling than most any other wood used. Desert ironwood is running a very close second. AS always...if anything of mine does come back I look at each one on an individual basis and make my assessment from there.
So if your planning on buying some snakewood and turning out a cue in 2 or 3 years with it............good luck!
And people wonder why these cues cost so much!
