The Metal phase, tested honestly — edge, handle, repair, and the cost over a lifetime.
The tool matrix says match the tool to the job's element. Under that sits a quieter question: how long will this tool stay true? Forged steel and composite are the two honest answers to that question, and they answer differently. This page is the field protocol for testing them ' + E + ' the criteria, the tradeoffs, and the old rule that decides between them.
Steel is the Metal phase with a memory. It rusts if neglected, it is heavier in the hand, and it asks for care ' + E + ' and it can be brought back from almost anything. A dull edge re-sharpens; a loose head re-handles; a cracked blade can be re-forged. Butcher Ding's knife was nineteen years old because it was kept true. The Amish buy steel and pass it down. Its weakness is the same as its strength: it asks for attention, and it rewards attention.
Composite is honest about being disposable. It is light, it does not rust, it asks nothing of you ' + E + ' and when it fails it fails whole: no sharpening, no re-handling, into the bin. Its edge is chemistry, not craft. For the tool that lives in the damp, hangs by the door, and must stay light, that is a fair trade. The question is whether the tool's life matches the task's element.
The test is not which is better; it is which serves the task and can be brought back when it dulls. For the tool that lives outside and does the heavy turning, steel earns its keep. For the tool that must stay light and dry-proof, composite is honest. Ask both questions before you buy: what is its element, and how does it get repaired? The second question is the one the old craftsmen never forgot.
Match the tool to the job, keep the edge true, and the tool outlives the task. See the Wu Xing tool matrix, the Cook and the Ox, or take the matrix with you — the Wu Xing Tool Matrix PDF ($7).
