Tungsten Carbide knives and High Speed Steel knives
D-Shore 80/85 hardness
Cutting sticks for guillotines and three knife trimmers
( i.e. WOHLENBERG ) wich are excected to last for long periods, or have to work under various
types of knives due the nature of material to be cut ( for: instance hardened or swedish steel ).
In the long run to use of white/yellow cutting sticks is therefore far more economical,
since all too frequent changes of the sticks are eliminated.
