When I talked to Curtis a year or so ago, he said that his stuff was made in Pakistan and was previously known as "pakkawood". What he referred to as dymalux was quite unkind to my gouges/lathe tools. I found myself re-sharpening multiple times to turn a single striker. With dymondwood, I can generally turn 6-8 strikers before sharpening. I use a skew gouge to round the spheres on my strikers, so it gets quite a workout on these strikers.
I have probably 15 blanks of the dymalux that I'm sending to another callmaker and paying the shipping. I haven't tried the softer material he offers. I think I'll just stick with the dymondwood. He has some great color patterns, I just can't make myself turn anymore of it.
