Paper Knife Material

Standard
A low alloy steel, with limited life between regrinds, used on machines
with very low usage.

Standard Inlaid Carbon
 An alloy tool steel, which is manufactured from a composite, inlaid material, utilising the traditional two piece manufacturing method. The 1/8" thick alloy tool steel, laid into the soft backing material, provides sufficient rigidity and strength to ensure that standard paper knives will withstand the extreme cutting pressures of high lifts and coated paper.

Hi-Cut
 A High Carbon, High Chrome alloy tool steel which offers as much as twice the blade life of our standard inlaid carbon. This HCHC quality is often used for lower knives on six knife trimming machines.

Super Cut
 An inlaid High Speed Steel which is manufactured from traditional two piece composite knife blanks. The HSS inlaid knives are 62-63 Hrc, which is designed to improve blade life as much as five times that of Standard quality. This alloy is designed to be used under high production applications, to ensure an increased number of cuts between regrinds, thereby reducing cost per cutting hour.

Powder Material
 ASP and CPM are unique powder metallurgy manufactured steels that produce a finely grained material with improved wear and toughness properties over conventional steels. Specific grades such as ASP23 and CPM10V are ideal for knives and exhibit excellent slitter performance.

Carbide Cut
 An inlaid Tungsten Carbide Tipped knife designed to give as much as ten times the life between regrinds, compared to standard grade. These precision cutting tools must be under optimum cutting conditions for best results.

Micro Grain and Sub Micron
 These grades have been developed with increasing wear properties prolonging the knife edge life. In the correct working conditions edge life can be improved up to 2- 3 times that of conventional fine grain carbide. This option must be discussed prior to ordering.
