Done correctly, the result is a blade whose hardness is sandwiched within malleable layers that absorb shock and give the whole resilience; but the operation requires the flats to be cleaned before each refolding, lest oxide scale weaken the core and cause it to split on impact like a wand of whalebone. Few smiths had the skill and patience to forge such blades; few purchasers had the wealth to pay for so much expert labor.

But this stranger seemed to think Samlor fell into the latter category-as the caravan master indeed did, if he wanted a thing badly enough.

The blade was beautiful. It was double-edged and a foot long, with the sharpened surfaces describing flat curves instead of being straight tapers like those of the knife in Samlor's hand. The blade sloped toward either edge from the deep keel in the center which gave it stiffness-and all along the flat, the surface danced and shimmered with the polished, acid-etched whorls of the dissimilar metals which comprised it.

Because of their multiple hammered refoldings, the join lines between layers of iron and steel were as complex as the sutures of a human skull. After the bar had been forged and ground into a blade, the smith polished it and dipped it into strong acid which he quickly flushed away.

The steel resisted the biting fluid, but some of the softer iron was eaten by even the brief touch. The iron became a shadow of incredible delicacy against which the ripples of bright steel stood out like sunlight on mountain rapids. Even without its functional purpose, the watermarked blade would have commanded a high price for its appearance.

Samlor's eyes stung. He blinked, because in the wavering lamplight the spidery lines of iron against steel looked like writing.

The stranger smiled more broadly.
