Thank you Dana, Greg, Gordon, Frank and Bear.
Bear, I have never worked osage (in europe is not an easy wood to find) but some day I will give it a try, sure.
Gordon, the handle is made remembering a truly nice handle work that I saw in ferret's archery web page, in the begginings of my information searching, and there was a german (Chris Guenther, I think)(in the section awesome wooden bows) that made a beautifull elm bow, with a handle that is the inspiration of this one.
Bye, american brothers,
David
