Shaving with an Obsidian Razor


(Video Link)


Some of you sissies are still shaving with sharpened shovels. But Mike Cook does it old school--as in using Stone Age technology. Watch him knap a slice of obsidian off a block and then shave his face with it.

Cook refers to obsidian as "the sharpest substance known to science." I don't know if that's true, but at the link, you can see electron micrographs of a surgical scalpel and an obsidian blade. The obsidian appears to have a sharper edge.

Yeah, it is true - the sharpest thing we have discovered is actually ancient tech - until we discover how to make a nanotube blade, I think we have the best we can use in obsidian. Sort of cool. Copper is also making a comeback in the operation theater as it has natural antimicrobial properties...

Well, see; You turn the handle up there and it turns this handle here, and the other handle, uh... No, that's the one you hold there and it... Wait, give me a hand here. You hold that while I... Hey, what's that adjusting thing there? Go ahead and try it... Doh! Now you've messed it up, see? It'll never work now!

Down on the farm toothpaste was ordered via the Sears Catalog, and was a luxury item. Back when people brushed their teeth once a week whether they needed it or not, this was also sold in the catalog as a toothpaste tube squeezer so you could get every last drip.

When television was first invented, lazy people were begging for a way to change the channel when they didn't have kids around to do it for them. Early developers considered the use of multiple connecting handles the best way to keep the television controller functional in different seating situations.

Unfortunately, the lazy culture of the time found these controllers too complicated to master, and decided to just keep the children home from school and available to turn the set on and off or change the channel for them. This is why most adults in this country can barely read or write or think for themselves.

It's ironic that should show up here. It was designed for the Writer's Workshop of Ashville, NC. It was used in a class as the McGuffin for a story to be made up on the spot, and thus is known as a "hack saw."

This is a Japanese torpedo winder from WW2. You know when those torpedos are shot in all the war movies? THey never how you scenes of the sailors laboriously winding up the little propellers. The US navy were the first to have electric torpedo winders, although early in the war they malfunctioned and wound them the wrong way so they ran backwards and sometimes hit our own subs. Today's submarines come with pre-wound torpedoes.

It's a handlizer, produced by DARPA in 1979 as inspired by the writings of Dr. Seuss. It's three levers that, when turned or pulled, simply move another lever.
