could be, there are some spots in the heartwood that were very dark, almost black. it was fun working on though, and i know i did my best tillering it so no big deal, the next one up has no heartwood and was very much healthy when i harvested it. will be my toughest stave to work yet because of character, but it will be fun nonetheless. im salvaging a few bits from the broken one though, might be able to use them on some of my other woodworking projects.
