I also got this an axe not an adze as I mentioned earlier. I was of a mind to take it apart but thought lets just have a go at the glue showing around the blade with some petrochemicals and acetone. Nothing happened!!!

this is an organic glue. Then with close inspection the on the rest of the item, this glue was clearly applied before the binding. As I got these ridiclously cheap I gave a lump of wood a good hard whack just for fun

. You would not want to be hit by this thing. As good light is fading It will be tomorrow before I can show some more detailed pictures. There is another axe like thing that has a bone blade I will also look at to.
