Resharpen when cut size drifts, throughput drops, or the blade stops producing a clean cut. Abrasive or contaminated feed such as mineral-filled plastic, metal, or tire dulls edges faster than clean plastic, so high-wear lines regrind more often. Scheduling a regrind before the edge fully rounds over removes less material and extends total blade life.”}},{“@type”:”Question”,”name”:”When should a blade be reground instead of replaced?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”Regrind as long as the blade still has usable steel above its minimum dimension and the body has no cracks or chips too deep to grind out. The RT-1600 restores the edge to 0.03 mm precision, so most knives can be sharpened many times before reaching their wear limit. Replace only when the blade hits its minimum size, develops structural cracks, or loses its hardened layer.”}}] }
