I picked up something I hadn't seen before on a camping trip with my wife this past weekend. We were in our canoe quite a ways off the road system and ended up sharing river banks with a couple beavers. I brought home a few sticks of beaver trash, fresh birch sticks with the bark scraped off in a very orderly workmanlike fashion.

First pic is the bare wood, still quite damp I am afraid, it was live when the beaver cut it off the tree and still damp with beaver spit when I pulled it off the riverbank. I whittled a few knife handles on the riverbank as vacation activity. They are drying rapidly but not cracking yet. Second pic is same handle with damp epoxy on one end and all the way down the sides. I'll see if it cracks in the next few days.

If it holds together ok I'll likely drill the end with no epoxy on it yet and epoxy a blade into it.
