Rick, I do not own any of the trapdoor autos but I have handled quite a few of them. They have quite a bit of weight to them, they have a very solid feel. I can also say that these are the most unique autos I have probably seen. At the Blade show I went back to his table several times. These knives are flawess, and they have very attractive lines. The trapdoor button feature is definitely the icing on the cake! The button has contours and patterns that match perfectly with the handle and when you first pick one up you have to look for the button. I can honestly say that if I had $1400 to spend at the Blade show I would have bought one of his knives.
