If you use a lot of blades on a regular base, this is the OLFA® knife for you. This knife holds up to five blades for up to 40 fresh cutting edges in just a snap. When a blade segment gets dull, simply snap it off for a new one and continue working. When you have used all of the segments on a blade, just slide the blade actuator forward to eject the blade and then slide it all the way back to automatically load a new blade. This knife is great for cutting heavy-duty materials such as drywall, linoleum, carpet, flooring, insulation, and roofing. (PL-1, #5021US)
