Top Slitter Knives amp; Blades | Paper Converting | IKS
Manufactured from a powdered metallurgy, SPS knives provide an ultra finegrained microstructure, which can be ground into the keenest edge possible. In addition to being the sharpest standard slitter knife we have ever produced, SPS knives last up to 10 times longer than other knives. They are also flatter than any other knife (less than .001).
