Sumac has a bit of a curly/twisty growth habit, as does lilac. They’re quite different woods, the former soft and brown green, the latter hard and white purple. Old dead things though, I was clearing old brush and thought I had a great old lilac and that the wood had discolored with age. Not so. It took surprisingly long to clear the misapprehension.
I did make a knife/stirrer out of a piece.
It was the working characteristics, and the absence of the very distinctive smell of lilac wood, that finally hipped me to the present reality. It’s funny how strongly a (potentially false) first impression shapes belief.
It’s staghorn sumac. Not really the right kind of wood for a kitchen implement, but then again I only made it thinking it was lilac. This is one way a nonesuch can be born.
