Prosthetic Conscience

Yankee Screwdriver

I’m really interested in appropriate technology; that is, the right level of technology for the task. For example, for making trips under about five miles, especially with a limited amount of cargo, and in good weather, a bicycle is clearly better than an automobile. With a canopy, a cargo trailer, and flywheel assist with regenerative braking, it would be even better. Likewise, a reel-mower is much more sensible for a small lawn than a power mower is. You see where I’m going with this; I love the idea of using human power for things, but with appropriate mechanical technology to get the most possible efficiency out of it, and more power than conventional hand tools. For a lot of things, motor power, whether it be electrical or combustion, is just an excess, and anything excessive is waste.

So, what does this have to do with a Yankee screwdriver? A Yankee screwdriver (Google cache if the site is down) is another name for a spiral-ratchet screwdriver. That’s a screwdriver with interchangable bits, like an electric screwdriver, except that it’s human-powered. Instead of twisting it, you push it, which is easier on your wrist and carries more power. This is a great idea. However, apparently, actual Yankee screwdrivers are now sold only in Britain! So failing that, I’d like a nice ratchet screwdriver, which is not quite as good as a Yankee screwdriver, but better than a fixed screwdriver, since you don’t have to keep changing your grip on it. I found a nice one on clearance at the Hardwarehouse for $4.00, with magnetized bits (very useful); the only not-so-good thing about it was that it had a very chintzy plastic carrying case. I imagine you could find a decent one for about $10, or a good one for under $20.

Update: Apparently the Garret Wade company is importing Stanley U.K. Yankee screwdrivers. The small size is just under $50; possibly someone makes one for less? On the other hand, maybe a garage sale or antique store would be a better bet?
