Heres the finished adze I tried it out on a piece of oak and it works pretty good. I finished the blade and cleaned it up. Then I cut the channel for the tang and cut out a wedge from the ancient wooden carpenter plane. A piece of para-cord and its all done. I see that keeping it tight is going to be a continuous exercise but thats the simplicity of the wedge. It was a lot of fun making this thing.
I really like this guys idea and his pocket adze and pack adze: http://woodsroamer.blogspot.com/2011/02/pocket-adze.html
