One or two segments out; break at the groove the moment cut quality drops. Fifty blades is permission to snap freely — use it, because a rationed snap is a torn workpiece.

Disposal is a bigger problem at this volume, and this pack does not solve it
Fifty blades snapped down to their stubs is a lot of the sharpest small waste a jobsite makes, and the 50-pack is not built with a used-blade chamber. A crew running bulk 9mm blades needs a sanctioned sharps container at the work — snapped tips go into it directly, never into pockets, onto drop cloths, or loose into trash bags that they will slice open. Where contained disposal has to be built into the package, that is the 42356 ten-dispenser's job, and a smart setup pairs the two: the 42352 as the resupply, the 42356 (or a shop sharps bin) as the disposal point.
03
Carbon steel, kept dry
Thirteen-point carbon blades hold a keen slicing edge and rust if stored wet — keep the bulk box dry and wipe the working segment after paste or wet work. Discard rate outruns rust in practice; the exception is a blade left loaded in a knife between jobs.
Asked at the counter
BUYER QUESTIONS ANSWERED BEFORE THE CART, NOT AFTER THE RETURN
How many edges is fifty blades?
Six hundred fifty: fifty blades, thirteen snap-points each.
Is the bulk blade the same as the five-pack blade?
Identical — same carbon steel, same thirteen points. The only variables across the 9mm packs are quantity and packaging.
Is it a dispenser or a flat pack?
The catalog says "50-Pack"; the store title says "50-Blade Dispenser." We can confirm fifty blades; the reusable-dispenser-with-hang-hole form is documented for the 18mm 50 (42359), not for this SKU .
Where do the used blades go?
Not into this package — it has no chamber. Use a sharps container, or pair with the 42356 dispenser.
Should I buy this or the 18mm 50?
By blade, not by count: 9mm for paper/film/precision, 18mm (42359) for board/foam. Both come in fifties.
Do they rust?
Carbon steel — keep the box dry and wipe the working blade after wet work; you discard long before rust matters.
