How To Snap-off Utility Cutter Blades
Olfa Utility knives are used commonly for cutting a range of materials like paper, card, fabrics, textiles, foam, carpet, underlay, plasterboard, thin plastics, balsa wood, tape, wallpaper, shrink wrap, PVC, vinyl, leatherette, vinyl flooring, window tint, car wrap etc..
When the quality of the cut is not smooth and the utility knife feels like it is dragging through the material been cut instead of cutting through, it is time to snap-off the blade to expose a new sharper edge.
Olfa blades are pre-scored at 1cm segments; when the blade or tip becomes blunt simply snap the blade at the next segment to expose a new sharp tip and edge.
Caution: The blades on Olfa cutters and knives are extremely sharp and will cut through your fingers like a hot knife through butter so take extra care when handling the blades. always use safety glasses when snapping a blade segment. A blunt blade or broken segment may not look sharp but is still very sharp to cut your skin.
You must never at any point try to snap-off a blade segment using your fingers even if you are wearing gloves, always use a pair of pliers to hold the part of the blade you want to snap-off.
