Bin and jigsaw blades Jigsaw blades are largely viewed as consumable products that are thrown away once they have become dull and lost their cutting ability.

Because they are fairly inexpensive, it is much more cost- and time-efficient to replace the blades rather than to restore their teeth by sharpening.
