Here's a professional artist's portrait of the model Keith just bought:
We used to have a poster of these concepts up on the wall when Kirby was little:
LeverWhen I tried to look up the list, I couldn't find it. I was looking for Greek and tool, but if I'd looked for Renaissance and machine I would have found them.
Wheel and axle
I called Keith to see if he could help. I was saying "incline, wedge, lever," and I said "I think there are six of them."
Keith said "screw," and I said a screw was an inclined plane in a spiral, but he said no, it was separate. So I believed him, kind of, and he told me about an article he had just read about the way the thinking and skills of younger people (tech natives) has changed. We talked about that a while, and then got off the phone.
I googled a bit more and then thought IF I were going to actually get up and look, I wouldn't look for that poster. I don't remember if it was rolled or folded or one of the heavy flat ones from Colborn's, a long-out-of-business educational supply house from which we used to get things like tempera, games, Dover coloring books, and single crayons. So I thought the place to look, in our fairly-vast home library would be an older encyclopedia. Yes! So I went to Wikipedia and found this, as a link from tool: http://en.wikipedia.org/wiki/Simple_machine
So those are not about tools, but about "machines." Yet an axe is a wedge, used all of a sudden.
This is all plenty exciting to me, because I'm easily amused and I love these little hunts and connections, but honestly, the definition of "tool" and the concept has expanded since I was a kid and was told to memorize what a tool was. When I was a kid, humans used tools and that made us human, but that's no longer "the truth." Chimpanzees can use a leaf as a sponge to gather water out of a hole. They will lick a stick and put it down a hole to collect insects (termites? ants? I don't know what). They will move things to climb up on to get something they can't reach.
Marty says he thinks maybe elephants will pick up a stick to knock something down that's higher than their trunks. If they haven't, they should.
So what, these days, are "tools"? My computer? Google? Wikipedia? Blogger.com? My new glasses? That electric teakettle I'm about to go and heat water with?
We talk about parenting tools, and people adding to their toolboxes, and those are all in the realm of thought (and action proceeding from thought, but without physical tools).
I'll add pictures of my own little hatchet/handaxe...
Those are the two places it lives, by the fireplace or near the woodpile for the hot tub. I've had it for twelve years now.

The link was gone, but there's quite a bit more, now (2022) on designer axes, so I replaced it with a google search.
