Upper/Male Slot Knives
RECESSED
Recessed for "Auto Set" Machines.
SupaClean™
A very sharp edge profile, delivering super clean slots on all board grades. Handle with care!
Piranha Tooth™
A fine-tooth serrated edge profile. Achieves a superior slot on lower grade board, and becoming more popular as paper weights reduce.
Wavi Edge™
Clean sharp cutting action from the patented ‘Wave’ profile. A sharp cutting edge without “sawing” therefore reducing dust and safer to handle. The absence of pointed serrations means the cutting edge is stronger and withstands wearing forces longer, while also reducing lower / female slot knife wear.
SerriTip™
Is a precision machined serrated tip, designed to help with achieving a cleaner and more precise start and finish to the slot cut.
UniTip™
A unique feature upper slot knife with a replaceable tip end. Quickly rotate or replace the serrated tip to keep slot quality optimised, reducing costly early knife changes.
Lead-in Chamfer
Proven to help the upper slotting knife engage whilst causing less damage to the lower slotting knife.
Bevelled Edge
Enables more controlled waste management.
FCO Pocket
Flap Cut Overlap Pocket designed to work with the Shok Blok® system for a positive overlapped cut of both slot and flap, ensuring removal of any tab waste still attached at the corner.
Leading Under-Cut Tip™
The lead knife with the Leading Under-Cut Tip™ feature provides a cleaner cut to complete the first slot cut. See spec sheet for more details.
