How does T10 clay-tempered folded steel differ from 1000-layer Melaleuca steel?
Updated Feb 2026
T10 clay-tempered and 1000-layer Melaleuca steel represent different approaches within the folded katana category. T10 clay-tempered is a specialty steel grade with superior grain response to the differential hardening process, meaning the clay application and water quench produces a clearly defined and active hamon. A T10 folded clay-tempered katana prioritizes the hamon as its primary collector credential alongside the folded construction. Melaleuca steel is pattern steel produced from folded layers of multiple steel types - its primary visual characteristic is the surface pattern created by the layered construction, where different steel types create visual contrast in the layered grain. A 1000-layer Melaleuca piece prioritizes the layered surface aesthetic as its defining quality. Both are genuinely folded constructions, but they emphasize different aspects of what folding achieves.
