Chandler and Price Replacement Blades

Common signs include fuzzy edges, incomplete cuts at one end of the stack, increased pressure, paper pulling, visible chipping, or a gradual decline in cut quality. Before removing the knife, confirm that the stack is properly jogged, the clamp is holding the material securely, and the cutting stick is not deeply worn. A dull knife may still cut thin stacks while failing on heavier lifts, which can make the problem seem inconsistent. Inspect the edge under safe conditions without touching it directly. If the knife is straight and has enough usable height, professional sharpening may restore performance. Cracks, bends, serious chips, or excessive prior grinding generally point toward replacement.

Inspect the cutting stick, knife bolts, clamps, guides, back gauge operation, guards, and any surfaces used to align the stack. Worn hardware or a damaged cutting stick can prevent a new knife from delivering an even cut. Clean away paper dust and debris from accessible areas without disturbing calibrated components. Cutter accessories may include supporting items for maintenance and material handling, but every part must be suitable for the specific machine. Do not substitute ordinary hardware for blade mounting components. If a bolt, thread, guard, or adjustment mechanism appears damaged, the cutter should be evaluated before normal operation resumes.

Store the knife in a rigid protective case with the cutting edge fully covered. The container should be labelled with the cutter model, blade measurements, sharpening status, and any installation notes. Keep it in a dry, secure location where it cannot fall, be struck by other equipment, or be handled by untrained staff. The knife should not rest directly on its cutting edge. Use suitable lifting and handling equipment when moving a heavy blade, and never carry it loose through the work area. A clear storage system also prevents similar blades from being mixed together. Before installation, inspect the knife for corrosion, shipping damage, and the correct bevel orientation.

The cutting stick supports the bottom of the stack as the knife completes its stroke. Deep grooves or uneven wear can cause incomplete cuts, especially along sections where the blade no longer meets a firm surface. A worn stick may make a sharp knife appear defective and can encourage operators to set the cutting depth too aggressively. Inspect the stick whenever cut quality changes or a knife is replaced. Depending on its design, a stick may offer several usable surfaces through rotation or repositioning. Correctly sized paper cutter cutting sticks should be matched to the machine dimensions. Replacing or rotating the stick at the proper time protects the blade edge and improves cutting consistency.
