I scavenged it from their firewood pile, and it was still pretty dang green. I think it weighs about half now what it did when I grabbed it.
I strongly recommend finding a branch and making your own whacker to suit you and your hands. You’ll find a preferred side and if it’s too big, you can make it smaller. If it’s too small, try again. Oak is probably better than birch, but birch works.
