dwardo, it will be a few days before i can post more pics, but the front profile is pyramid shaped - 1 3/4" tapering to 1/2 at tips. I have a 5 inch handle area. White oak is good stuff - extremely tension strong. I think you could tie it in a knot before it would break. It responds well to heat treating and, actually, would probably have excessive string follow without it. Just my 2 cents...
Thanks Dell, it is different than any of the other oaks that we have in the states as well. It may be a lot like your wych elms? Responds well to steam and heat.
