It's been starting to take off a bit, lately. I think that there are a few facets that appeal. Not to sound like an old fart, but I think that a lot of it is somewhat due to being raised in a throw-away society. For the people that intend to use them, there's not only the appeal of making something with your own hands, but the appeal of having something that could last generations, as opposed to the Ikea stuff that you throw in the dumpster when you have to move. Even if you're not going to use them, there's something cool about a highly-functional tool that's decades, or even centuries, old (this plane has a production date somewhere between '55 and '66, making it pretty "young" by some standards; I recently picked up a late 1800s saw that I've cleaned, tuned and is ready to use).
