Damascus steel (Arabic: فولاذ دمشقي) refers to the high carbon crucible steel of the blades of historical swords forged using the wootz process in the Near East, characterized by distinctive patterns of banding and mottling reminiscent of flowing water, sometimes in a "ladder" or "rose" pattern. "Damascus steel" developed a high ...
An image of a modern pattern welded knife blade, showing the dramatic patterning on the side below, and the layering of the steel in the spine above. Acid etching darkens the 1080 plain carbon steel more than it does the 15N20 low alloy nickel steel, producing alternating bands of light and dark on the surface.
Damascening is the art of inlaying different metals into one another—typically, gold or silver into a darkly oxidized steel background—to produce intricate patterns similar to niello. The English term comes from a perceived resemblance to the rich tapestry patterns of damask silk.
Wootz steel is a crucible steel characterized by a pattern of bands and high carbon content. These bands are formed by sheets of microscopic carbides within a tempered martensite or pearlite matrix in higher- carbon steel , or by ferrite and pearlite banding in lower-carbon steels.
William Francis Moran Jr. (May 1, 1925 – February 12, 2006), also known as Bill Moran, was a pioneering American knifemaker who founded the American Bladesmith Society and reintroduced the process of making pattern welded steel (often called "Damascus") to modern knife making. [1] [2] Moran's knives were sought after by celebrities and heads ...

This often resulted in an intricate pattern when the steel was forged, filed or polished, with possibly the most well-known examples coming from the wootz steel used in Damascus swords. The steel was often much higher in carbon content (typically ranging in the area of 1.5 to 2.0%) and in quality (lacking impurities) in comparison with other ...
