Of course it's a tool. I don't think anyone disputes that. But it is much more than a tool to many of us. While some may collect framing hammers and crosscut saws, you don't see anyone agonizing over refinishing and recheckering the wood, much less upgrading it to quarter sawn English Walnut and applying 27 coats of hand-rubbed witch's elixir for a perfect finish nor polishing metal to 1200 grit for a flawless bluing. Nor does anyone engrave them with pictures of construction site dogs and roofing trusses. Nor are there nearly so many websites devoted to them in all their technical intricacies, histories, and tradeoffs in capabilities etc.
If it's just a tool, then I'm sure yours bounces around in a tool box between your pipe wrenches and lineman pliers, eh?
