（重定向自Butcher steel）
A honing steel, sometimes referred to as sharpening steel, sharpening stick, sharpening rod, butcher's steel, and chef's steel is a rod of steel, ceramic or diamond coated steel used to realign blade edges. They are flat, oval, or round in cross-section and up to one foot long (30 cm). The steel and ceramic honing steels may have longitudinal ridges, whereas the diamond coated steels are smooth but will be embedded with abrasive diamond particles.
