Considering that there's a finite supply of old tools, every one taken out of circulation diminishes the pool, and reduces the opportunity for people to use and appreciate them. I thnk we lose a little bit of our heritage, our history, when that happens, and get even further disconnected in a world that could more connections of that sort, not less.
Your thoughtful post has prompted considerable thought and exploration. I too am a tool guy, with stories of taking things apart around the house, in between learning to walk and talk. I grew up with a family culture of hard working tools, including axes. Some of my favorite moments in life were accompanied by the use of tools, and some of my saddest, most stomach turning moments were when so many tools (hand tools especially) devolved into cheap starter set quality.
I've spent some of the last few years (usually in the summer), swearing at the state of the modern fan industry. Laid to waste by air conditioning technology, a once vibrant industry has shrunk down to less than a handful of companies who still even bother to use
metal. So to with axes, company after company decimated by the advent of the chain saw. Prior to this, companies competed for the hard working dollar of professionals and heavy duty homeowners, expecting a lifetime of use. Those same professionals can now cut 100x the wood in the same time, with less effort, leaving the market to casual home owners and recreators, with different goals and different budgets. Searching, the only company I find, still producing (in the US) axes of similar design and construction to the early 20th centery is
Council Tool. An anomaly, made possible by the continued patronage of the US Forest Service.
So what we're left with, is a supply, left overs from production between about 1850 and 1950. Produced by the companies and people and skills, largely lost to history. Sitting on benches, in tool boxes, on barn floors, and in the corners of backyards. Some people see them and know enough to put them on ebay. Others see the worst only as rusted squares, left to rot or worse - sent to trash or recycling during a room or yard cleanup. Which leaves the dilemma: if the goal is to preserve such tools, what will create the most value, the most incentive, such that the most number and variety of tools see the most rescue?
I for one, have decided to support the remaining industry, helping ensure production methods continue to live on, adding to the overall pool of quality tools.
