Our Gray Tanto collection features three primary steel types. T10 carbon steel is a high-carbon tool steel prized for its hardness (typically around 60 HRC) and its ability to hold a vivid hamon temper line through differential clay hardening. Pattern-welded steel is created by folding and forge-welding multiple layers together, producing visible grain patterns in the finished surface that make each piece visually unique. Damascus steel follows a similar layered forging process but often incorporates contrasting steel alloys to create bolder, more dramatic patterning. All three steels are well-suited to display-grade collectibles because they accept a high polish and develop character over time with proper care.
