Hey Ranger,
I ALWAYS let my wood sit at least a year before I work it....snakewood included. Snakewood always seemed a little "brittle" to me anyway, but I love it, as it makes one beautiful set of handles. I seal it with a friction finish I get from Penn Woods prior to buffing it. I only buff with the White Matchless stuff...it is my final buff on metal, wood, etc...I never buff with the coarser stuff, as it will darken it and screw things up. The friction finish is what the fancy ink pen makers use while the pen barrels are still on the lathe.
I had a similar problem with some olivewood that I got from South Africa @ the Blade show...every piece I had warped/lifted after it was sold. Learned my lesson well after that...had to replace each piece. Now, anything that is not stabilized, horn, antler, ivory, fancy wood....it sits for at least a year.
Are you and I the only Rangers on this board? Hope it helped.
Rangers Lead The Way,
Hank Hammond
