What it does
Five carbon steel 18 mm snap-off blades, 8 points each, 40 edges in all. The same blade as in the 18mm 10-pack and 50-pack.
How to use it
- Keep the blade short for scoring. Extend it in a locking knife for deep foam passes.
- Snap a segment the moment the edge tears instead of cutting.
- Put spent segments in a sharps container.

Common questions
Why 8 points when the 9mm has 13?
An 18mm blade is snapped less often than a fine 9mm blade.
Can I extend it a long way to cut foam?
Yes, in a knife that locks, such as the 42047. Do not run a 9mm blade far out.
Does the pack store used blades?
No. Use a sharps container. Only the 9mm 42356 has a used-blade chamber.
Will it fit my knife?
It fits any 18mm snap-off knife, including the 42047.
