Melaleuca steel refers to high-carbon steel that has been repeatedly folded and consolidated during the forging process, producing a blade surface covered in flowing, layered striations reminiscent of wood grain or tree bark - which is where the "tea tree" name originates. Each folding pass doubles the internal layer count, so a blade folded ten times contains over a thousand distinct layers. The result is a surface pattern that is entirely unique to each individual piece, impossible to replicate exactly, and visible to the naked eye once the blade is polished. This is why collectors specifically seek melaleuca-forged blades: the pattern is not decorative printing or acid etching but a direct expression of the smith's forging process, making the blade a permanent record of that handwork.
