6 ABOUT THE BLADE
If the blade becomes dull
When the blade starts to lose its sharpness, try gradually increasing the blade force (refer to page 8, "4-6 Cutting Test to Check
Blade Force").
Increasing the blade force temporarily allows the blade to perform better. However, once the blade no longer provides reliable
cutting, it is worn out. Since the blade is expendable, it must be replaced as often as necessary.
Average blade life
The life of a blade is determined mainly by the amount of cutting it performs. The following table shows the average life of
blades.
The total cutting length actually obtained can vary considerably depending on the thickness, toughness, and type of adhesive
layer that the sheet has. Set an appropriate blade force, one that is well matched to the type of sheet and hardness of the blade,
and the life of the blade will be extended. Excessive blade forces can cause the blade to wear out quickly. Care should be
taken.
