Stone tools of the past worked better that steel tools of the present.
I assure you, I didn't read it with one.
Obsidian blades can be extremely sharp, but to manufacture them to a standard that make them "worked better that [sic] steel tools of the present" is not feasible. Do you have examples of stone tools working better then modern steel ones? Oh, sure, a bit of obsidian might work better than the little, plastic sheathed scissors the orderlies allows you to cut the yarn and construction paper with for your macaroni projects, but not real, steel tools. Someone is selling you an inferior bill of goods; your comment is a Luddite fairy tail.
I've read every one of the 54 posts you've made to this forum to date. Not once have you made a point that is anywhere close to the equal in beauty of any of a dozen of things I've read in the April 2008 Scientific American I'm reading today. (While Straggle has several times in his last few posts, so it can be done.)
If the greatest wonder you get out of this world are based on willful ignorance of the workings of this world maybe you should work harder on getting a pair of real scissors.

17 But of the ponderosa pine, thou shalt not eat of it; for in the day that thou shinniest thereof thou shalt sorely learn of thy nakedness.
