And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
I've read that some surgeons prefer stone knives because the blade is finer than the stainless steel scalpels and causes less damage. There's somewhat of a resurgence of stone tool making.
Yes indeed, SiG. I have talked with a surgeon who had tried using an obsidian blade for surgery and it was so much sharper that it didn’t have the familiar tension he was used to in a scalpel. Another surgeon wanted to improve a regular scalpel by coating it with Teflon and had improved results until blood coated the Teflon coating. He ended up heating the coated blade so it would cauterize the wound and limit the blood that caused the problem. Because my wife is a nurse, we have a few single-use scalpels in her kit. I haven’t tried to buy stone scalpels, so I don’t know how prevalent they might be.
I have made stone tools but I am not Neanderthal old but I may have early onset rigamortis

DeleteI wonder, can you chip out a commutator stone? :)
ReplyDeleteDon't know about stone tools but I do remember Raquel Welch in 1 Million Years BC.
ReplyDeleteDon't We All!
DeleteYeap Yeap…made both stone tomahawks and stone tip spears as a 6-9 year old roaming the hills of Harland County, Kentucky… a fledgling Neolithic…
ReplyDeleteYep, you should have heard the grunts of amazement when I started making sparks! And after the fire got started all the women wanted me! Ugh Ugh !
ReplyDeleteI was a math major and they made me take an arts course and I chose the history of technology.
ReplyDeleteBest course ever.
Prof taught me how to flake glass blades from miscellaneous rocks, none of which I remember, but also, -- beer bottles!
