Not sure about the purpose of this article. If it's for education ("101") then some fact-checking would be nice. For example, copper is too soft for proper blades - perhaps the author was thinking of bronze...? And folders were popular in ancient Rome, and have been found in digs from ~500 BC. And so on.

YogaBearQuick research suggests copper was indeed used as a blade, axe, and tool material before bronze was in widespread use, either in pure form or in naturally forming alloyed states. Given that the earliest dated use of copper is 4000 years before the earliest use of bronze, I'm not surprised. Copper is quite soft as far as metals go, but still superior to stone for many applications, and only gold and meteoric iron were discovered before it, neither of which was abundant or particularly more useful. The iron in particular wasn't as we know it today: rife with impurities and a far cry from modern steel, ancient iron even at it's peak in the iron age was either very soft or extremely brittle, depending on the manufacturing process, with meteoric iron quality varying wildly.

MDDogeHi, thanks for the information, interesting links.
I didn't claim that copper wasn't used for cutting implements - it certainly was, along with other metals - but there's a reason why we had a "bronze age" but no "copper age". Copper wasn't the gamechanger that bronze was.
Anyway, this was only a one-line comment on errors and inaccuracies in the text, and I fully agree that a complete discussion of "knives" can (does) fill several bookshelves!

MDDogeGreat information here - also, its important to note that Bronze doesn't exist without copper (bronze is copper and tin). Otzi the Iceman was found with a copper axe: http://www.iceman.it/en/axe

YogaBearIt depends a bit on what you consider a proper blade, but I agree everywhere bronze was discovered it replaced copper, so without a doubt bronze was superior to copper (for cutting tools) just as steel was superior to iron.
