Planning Guide

Plan the right fit before choosing

Start with compatibility

Select the correct blade type and fit

Replacement blades in this category are made for several tool styles. Standard utility blades fit most standard utility knives, while standard razor blades fit most standard razor blade tools. Other options are specifically designed for SK-8, SK-10, SK-4, SK-9, or compatible UTC-1 utility knives, or for most 25 mm snap-off blade knives.

  • Match specified safety-knife compatibility before selecting a blade.
  • Choose 9 mm, 18 mm, or 25 mm snap-off blade options according to the compatible knife.
  • Select a standard utility or standard razor blade for the applicable tool type.
Compare cutting-edge designs

Consider how the blade refreshes or extends use

Snap-off blade sections allow a worn section to be removed to expose a fresh point. Dual-edge blades provide two usable cutting edges, while SK-10 replacement blades offer four cutting positions. Round point safety utility blades are intended to help reduce accidental cuts during carton opening and help limit damage to box contents.

  • Choose snap-off blades for fresh cutting points from segmented sections.
  • Consider dual-edge or four-position designs for continued cutting before a blade change.
  • Use a round point option for safety-conscious carton-opening tasks.
Plan quantities and blade handling

Keep replacements organized for routine work

Pack formats include 3-pack, 5-pack, 10-pack, 50-pack, and 100-pack options. Several blade choices include a dispenser to keep blades organized and accessible. For used blades, the disposal container has a puncture-resistant body, a locking tethered lid, and can be placed on a surface or fixed to a wall with its metal rack.

  • Choose a pack quantity that fits the expected replacement frequency.
  • Consider dispenser-equipped options for organized blade access.
  • Use the designated disposal container for used blades; it is designed for use with 11-085 blades.
