My thanks to Tommy Dion for this amazingly beautiful looking AND beautifully sounding whistle!
It is a non tunable D whistle made from dymondwood, and I could not be happier with how it turned out! It looks fantastic, plays sweetly, and has a nice little heft to it, not like some of the wood whistles I have held (It’s due to the dymondwood being impregnated with resin).
Again, my thanks to Tommy for such an amazing whistle!
Dymondwood is fun stuff. Nice work Tommy.
BTW-- that smell will go away eventually 
I have a concertina whose frames are made with Dymondwood… I love the fact that it generally doesn’t look like a laminate. though I understand that Sweetheart had some issues with it when they made their professional out of it?

Nice. Tommy makes some beautiful whistles. How’s the overall intonation through both octaves, including c-nat?
I’m too much of a newb to answer that question, Tommy is an honest guy, and of course he’s played this whistle before he sent it to me, so maybe if he reads this he can answer this. 
That’s what I heard, but I have one of their Resonance low D’s in Dymondwood and it’s wonderful. I seem to remember Walt telling me that they had some quality control issues: some good stock, some not so good.
Personally, I haven’t had any problems with the stuff. I find that machining it takes a bit of care: sharp tools and small cuts, so it’s slow going but I’ve have only one or two bad cracks. It’s available in some REALLY wild colors too:
Thats cool… Is it much easier to care for than blackwood or Rose wood? It does make for a very handsome whistle.

Dymondwood is more moisture resistant than natural wood, but I still advise people to be careful with it. It can still break if you sit on your whistle. If you need REALLY tough, a polymer like acetal (Delrin) is the way to go although it’s nowhere near as pretty
