Cinderforging

A typical cinderforge's work area is black with remains of previous wood.

Process
Cinderforging is the process of taking a thick wood, most of the time ocane, and forging it with a layer of oset for protection. The wood then becomes hardened, and is sharpened, resulting in a cinderforged wood that is as strong as iron, and twice as sharp.

Etymology
The cinder, from Cinderforge comes from the leftover material of wood being forged in a cinderforge furnace, which adds to the fire to make it hotter.

Origin
Cinderforging is an ancient art, from before written word. It's rumoured the Celphs were the original cinderforgers, for their legacy of having a strong military, and winning many battles.

Cinderforging was forgotten when the Celphs mysteriously disappeared, and later picked up again by an ancient Lisian explorer who found cinderforged spears. They brought as many cinderforged weapons as they cound find, back with them, where other ancient Lisians reverse engineered and improved cinderforging.
