Perhaps the most important aspect of a paper cutter is the cutter knife. This part is absolutely essential to the cutting process. A good, sharp cutting blade can keep the cutter working at its top potential at all times, while a dull blade can significantly hinder its productivity. Our cutter knives are made from Solingen steel and can be resharpened a number of times before requiring a replacement. These blades are designed to be extremely durable and have a long life. Regularly having your knives sharpened not only extends their lives, but also the life of your cutter by keeping everything running smoothly. Additionally, most of the knives can be replaced without having to open up the cutting machine, making the process much safer and also easier. It is always a good idea to have a spare cutting knife or two around for when yours are sent out to be resharpened.
