Hey: As many of you I enjoy looking at tools. I saw an old one of these tools while visiting in the Azores recently. Found out that they are still made so I bought one, around 27 euros. It has similar functions to a draw knife, but not as much control, or an adz, but with a little more control. (At least in my yet unskilled hands) I looked up the website listed on the hardware tag.

I wish that I understood Portuguese.
