One of the fellows that I work with in Hawaii gave me a nice, large chunk of Koa a couple of years ago (about 2"x6"x4 feet - we had to cut it in half to fit it into my suitcase). I finally got around to making him something from it today.
Edger:
Your use of stashed wood reminds me that I need to look for my KOA stash and make something.
Very nice looking stopper.
