Our paper cutting knives are high-grade tools which
require careful treatment in regrinding.

To ensure efficient cutting qualities and long life, and to
avoid "burning" which results in chipping and cracking, the following
must be strictly adhered to:

• Use the correct adhesives.
• Sufficient coolant must be used throughout.
• Feed off the grinding wheel must be find and uniform.
• Frequent dressing of the grinding wheel is necessary.

After sharpening the burr should be carefully removed by
honing. The quality of the honing the useful life of the cutting edge
( see guidance of honing stones ).

Our paper guillotine blades are made from high chrome steel / HSS
/ TCT ( cutting zone ) with a soft impact resistant back. Post
heat treatment drilling and tapping guarantees the accuracy of
our fixing hole centres.

Our experience has shown that a standard bevel of 22^o gives the best results, but the following illustrations must be noted.
