Circular Knife Sharpening Service

Introduction Circular slitter knives lose performance through edge rounding, micro-chipping, pickup and repeated grinding. Immediate replacement is not always necessary. A dimensionally sound knife can often be resharpened, while a cracked, distorted or undersized knife may be unsafe to reuse. Base the decision on slit quality, measured condition, machine limits and service history. Quick answer: Resharpen a structurally sound knife when grinding can restore its edge within dimensional limits. Replace it when damage, distortion, excessive material loss or unstable performance cannot be corrected reliably.     1. Recognize the Cutting Signs of Knife Wear The slit edge is usually the first warning. Increasing burr height, tearing, inconsistent fracture or a repeating line d...
