This one is about 3 years old give or take. I didn't make it so I don't know exactly when it was, but it has been around for a couple of years. The wood hasn't cracked yet and it has been left in the car summer and winter.
Maybe we should talk to the maker and find out his/her secret?? Maybe you just got lucky?? I imagine there is not a 100% cracking rate for snakewood. Maybe you got one of the 5% that don't crack?? I just finished responding to a post on The Pen Shop forum about a snakewood pen that was crack free for 6 months.
I feel the need to find out about the mysterious Snakewod, I think that most of the problem is related to drilling, heat, and not being fully cured, but I'm going to find out, soon.
