For extra heavy-duty professional cutting, not any old blade will do. That is why tradespeople choose OLFA 25mm Silver Snap Blades for tough projects. Crafted from premium Japanese tool steel for unmatched edge retention and sharpness. Each blade includes seven (7) snap-off segments providing volume cutting. Each segment sports a deep-notched groove for easy snapping. Once a segment dulls, a quick snap reveals a fresh, sharp edge. Cut, snap, work with ease. These 1-inch-tall blades offer a universal fit and will work in most 25mm knives. Comes in a plastic storage case for convenience.
