What steel and construction standard do these Shusui replicas use?
Updated Mar 2026
The Shusui replicas in this collection are built with 1045 carbon steel blades, which contains approximately 0.45% carbon content. This grade sits comfortably in the mid-range of high-carbon steels: harder and more durable than stainless steel replicas, but still workable enough to hold the detailed blade geometry that collectors expect. Full-tang construction is a key feature — meaning the steel runs uninterrupted from the tip of the blade through the entire length of the handle. This is a structural hallmark that separates display-quality collectibles from purely ornamental pieces, and it ensures the replica feels substantial and well-balanced in the hand.
