Fire Hardened Spear

You know we always give recognition to the caveman, or woman, who harnessed fire, and invented a way to make fire, as well as the one who created the wheel. These people made a pretty significant contribution.

But what about the one who figured out fire-hardened spears? That's a pretty important leap in weapon's technology. To go from a throwing stick to a spear with a hard point. It keeps the weapon sharp, together and a far more useful in flight.

Somewhere along the line this caveman...or woman...stumbled on or had the idea to make fire hardened spears.

That's pretty cool. That and flushing toilets.
