Preventive maintenance programs plus qualified operators go a long way toward extending the lives of slitters and rewinders.

Grind Angle
Grind angle depends on the material being slit. Greater angles will allow a narrower contact of the blade into the web path, and will not disrupt the edge of the material.

Cant angle
In heavier stock, this angle is decreased to allow the denser material to pass the blade without slowing or stalling the blade from turning. In some instances, such as foil, a zero degree angle is used.
