I have compulsive addiction for treasure hunting, and an affinity for old tools. The strange thing is, this is all within maybe the last 6-7 months. It's funny that you say that axes are hot right now, but I don't doubt you as I have heard the same from a few antique dealers. I wonder why most got into selling them. Was it because they were hot and jumped onto the train? I don't know.
For me, I found this new love and this site by chance and accident. I'm a computer guy who hikes and camps for fun, I love the outdoors. One day I decided that I needed a hatchet and started to look at reviews on Amazon etc. My searches frequently turned up results on this site and bushcraftusa. I learned that many endorse finding a vintage piece to make their own, and I did. The unintended consequence is that I accidentally found the new love of hunting for treasures, and now I have to dig where others don't look and turn up all kinds of stuff. It's funny how one thing leads to another. In any case, I'm not here trying to cash in, I have a true previously undiscovered love that coincides by chance with a current boom. I have no carpentry background, skills, experience or training of any kind, and certainly no antiquing experience or background.
I do know this, I am meeting many interesting people in the estate sale/antique trade that I love to talk to as well as some great people here that I would never have otherwise had the chance to know, and I am learning many new things about history, people and tools of all sorts that I never knew that I cared about. I am learning about myself. I couldn't build a cabinet to save my life and my knowledge of tools was such that if I pounded a nail straight with a $3 hammer I was doing well. Now I am carving admittedly short straight handles with a knife by hand. Basic skills to be sure but it's a journey.
