Blue Steel

Blue Steel is a curious alloy known to few. It incorporates carbon, cobalt, and chromium into the alloy, causing a distinctive blue tint and a mirror sheen, even without polish. Blue Steel does not rust, and has superior strength to iron.

Blue Steel can hold a sharper edge than ordinary steel, and is therefore useful in armor-penetrating applications. It is also exceptionally resilient, and can be used in parrying maneuvers that would shatter lesser blades. In armor, this translates directly into greater soaking power.
