Easy-Cut Standard Replacement Blades are manufactured with the highest quality carbon steel and provide up to three-times longer lasting use. A special, patented radius blade tip helps to prevent injury and product damage when cutting. Blades do not chip and offer a sharp edge for up to 5000 feet of cuts, slicing through cardboard cleanly and easily every time! Replacement blades come in an easy-to-open dispenser, also used to store depleted blades for future recycling. A shipping label is provided inside the box to return blades when they have all been used. Each individual packet contains 3 blades: 1 for Easy-Cuts main blade carriage, and 2 for the handy spare blade compartment. (81 total blades per dispenser)
