2.2.3 Changing drag knife offset
A very important parameter for a drag knife is the offset. The offset is the distance
between the knife center and the knife tip.
NOTE: Knife offset should be set each time the knife is changed and should be
checked if the knife shows signs of wear.
Typical knife offset for Summa knives is between 0.41 and 0.45 for standard knives,
and between 0.9 and 0.97 for sandblast knives.
NOTE: Sandblast knives should be used when the material that needs to be cut is
thicker than 0.25mm.
