  • Precision and curves. Wallpaper, film, and tight radii want the slim 9mm tip (42345 / 42356 / 42352); an 18mm blade fights the curve.
  • Single-pass depth through thick board. For the deepest one-stroke cuts, the 25mm 42360 (in the screw-lock host) has more beam.
  • A wall fixture or a crew's week. Forty edges is a pouch supply; the 42355 ten-dispenser and the 42359 fifty-dispenser are the reusable, wall-living formats.
  • Hook or round-tip work. Pointed straight snap segments only — pulling flooring/roofing cuts (42200) and point-free safety cutting (42102) are other blades.

How the pros run it

01

Match extension to the cut

Short and fresh for scoring; long and locked for full-depth foam passes. The 18mm blade tolerates extension the 9mm cannot, but only against a host that clamps it — extension without a lock is how a deep blade creeps mid-cut.
02

Snap when the score drags

Break a segment the moment the edge tears rather than parts; eight points means you can afford the snap and still have a pouch pack's worth of edges left.
03

Used-blade discipline

A snapped 18mm segment is larger and easier to see than a 9mm tip, but it is still a two-edged piece of hard steel and it does not belong loose in a pocket, on the deck, or in a trash bag. This five-pack has no used-blade chamber, so drop spent segments into a sharps container. Among the 18mm packs, none carries a disposal compartment — the built-in used-blade chamber in this line is a 9mm feature (the 42356) — so 18mm crews handle sharps with an external bin as standard practice.
04

Carbon steel, kept dry

Eight-point carbon steel holds a keen edge and rusts if left wet; keep the dispenser dry and wipe the working segment after damp work. You snap past a blade long before rust matters, except the one left in the knife between jobs.

Asked before buying

BUYER QUESTIONS, ANSWERED BEFORE YOU ORDER
How many edges?
Forty: five blades, eight snap-points each.
Why only eight points when the 9mm has thirteen?
Because an 18mm jobsite blade is snapped less often than a fine 9mm blade — Hyde matches edge count to consumption, not to width alone.
Is this a different blade from the 18mm 10- and 50-packs?
No — identical carbon steel and eight points. You are choosing quantity and dispenser form.
Can I extend it a long way to cut foam?
Yes — that is the 18mm blade's advantage, in a host that locks (the 42047's positive lock). Do not run a fine 9mm blade far extended.
Does the dispenser store used blades?
No — fresh blades only. No 18mm pack has a used-blade chamber; that is the 9mm 42356. Use a sharps container.
Will it fit my knife?
Any 18mm snap-off knife, including Hyde's 42047.
