Well, apparently the Mesoamerican obsidian swords, like the Aztec Macuahuitl, were fearsome weapons, razor sharp and devastating for the unarmored human body.

But they were very brittle and couldn't stand a chance in a duel with the steel swords carried by the Spanish conquistadores.

I wouldn't go so far to advocate carrying an obsidian blade nowadays, but I admit I'm more and more attracted by traditional designs lately, not only in blades, but in every tool and utilitarian object.

Just a few years ago I too was mildly caught up in the whole "tacticool" fad, but I came to appreciate simple designs and natural materials. Maybe it's something one realizes with age?
