There is a lesson there, that I learned when I started woodturning.
At the time, there was gorgeous olive wood available. So, I bought a couple pieces for peppermills. Turned out great, but about six months had passed. That was mid-1990's, I have not seen the same quality olive since.
Recently, we have had that Honduran rosewood and some Concinna and Corrugata that were all extraordinary. But again, not to be repeated. Interesting when the "great" wood becomes available---GET it!!!
We are looking at a couple possibilities now, but they are always a guess, coming from halfway around the world!!
GREAT looking pen, Matt---wish we had more!!!
