Conan's Father: Fire and wind come from the sky, from the gods of the sky. But Crom is your god, Crom and he lives in the earth. Once, giants lived in the Earth, Conan. And in the darkness of chaos, they fooled Crom, and they took from him the enigma of steel. Crom was angered. And the Earth shook. Fire and wind struck down these giants, and they threw their bodies into the waters, but in their rage, the gods forgot the secret of steel and left it on the battlefield. We who found it are just men. Not gods. Not giants. Just men. The secret of steel has always carried with it a mystery. You must learn its riddle, Conan. You must learn its discipline. For no one - no one in this world can you trust. Not men, not women, not beasts... [points to sword] This you can trust.
And the Ironborn are a group of peoples that sail ships. They don't plant anything or produce any goods. They believe in order to get their wares they must pay the iron price. The iron price is by sword. That's the only way to legitimately earn anything.

I made this neck knife for my niece this past Christmas , from a piece of Texas Chert that a buddy of mine knapped for me. The edge was pretty darn sharp. I hand stitched the sheath with sinew that I picked up at a swap meet.
