It's European Yew (Taxus Bacchata), I think I of it somewhere on this forum, maybe even with you. It was a Yew branch, selected for cutting a bow. It matured and air dried for about two-and-a-half years. Then it turned out too thin and knotty fot that purpose. I sawed it off, measuring from the thin end, to fit the in-seam of my trousers. Not hat I would wear it there ofcourse but I like the whole ''Shillelagh'' -idea. I started cutting twenty cm. from,what was now the top, with my (very sharp) hunting knife. This sounds easy, I know. But it's rock hard and shine's immediately when carved under more than 45 degrees to the narural grain. After that, a very small-grain sandpaper and some oil and wax did the shiniest job! I live he feel of it when I'm walking with it and fel a hundred years longer.
