Oroshigane vs Aogami #1

Detailed metallurgical comparison between Smelted Folded Steel and Blue Paper Steel #1.

OROSHIGANE

Oroshigane

Smelted Folded Steel

Steel smelted and folded by individual blacksmiths in their own forge. Unlike Tamahagane from a centralized tatara, Oroshigane is entirely the creation of one smith — iron ore or scrap iron is smelted, refined, and folded to drive out slag. The result varies entirely by the smith's skill and chosen materials. Some legendary Oroshigane exceeds anything that can be purchased commercially.

AOGAMI-1

Aogami #1

Blue Paper Steel #1

High-carbon steel alloyed with chromium and tungsten for enhanced wear resistance and edge retention. Ideal for hard woods and heavy use. Forged by masters who prize its demanding nature, it rewards a skilled sharpener with extraordinary edges that outlast almost any other carbon steel.
