Why this chantry replacement steel earns its place
The steel is the part that does the work and the part that wears out. Every blade drawn through a sharpener passes across it, and over a few years of daily use the fine surface that grips the edge polishes itself smooth. Nothing looks broken when that happens — the knives simply come out of the sharpener no better than they went in, and a section that has been maintaining its edges properly starts finding that the knives are tearing instead of cutting.
Replacing the steel restores the sharpener to doing its job. It also keeps the economics sensible: a chef's knife loses its edge over a single shift, so a working kitchen touches its blades up daily, and a sharpener that no longer bites quietly drags the whole knife section down until someone notices that everyone has started reaching for the one knife that still cuts. Renewing the wearing part is the cheap end of that problem, and it takes a station back to a proper edge without a new unit or a trip out for regrinding.
