Purpose and user
This Westward 402L09 snap-off utility knife is built for electricians and tradespeople who need a reliable cutting tool on the job site. It handles drywall, roofing shingles, insulation and similar materials with a carbon steel blade designed for general purpose use. The 5 in length gives extra reach for awkward cuts. A snap end cap allows quick blade changes without extra tools.
Capacity and limits
The blade measures 23/64 in. wide and 5 7/64 in. long, with an overall width of 7/16 in. for a secure grip. It comfortably slices through common building materials but will dull faster on abrasive surfaces or heavy sheet metal. The snap-off design extends usable life by exposing fresh edges, though the blade itself is not replaceable with standard segmented refills.
Deciding spec
The snap-off mechanism with a carbon steel blade is the feature that determines fit. Buyers who want a fixed-blade knife or a model accepting standard trapezoidal blades should look elsewhere. This knife is restricted from sale in California due to Proposition 65 chemical warnings for cancer and reproductive harm.

Questions about this item
Will the 5 7/64 in blade reach past the 7/16 in grip when I keep my older utility knife for scoring?
The blade extends 5 7/64 in from the 7/16 in wide handle, giving extra reach beyond your existing knife for deeper cuts in drywall or insulation.
How can I confirm the carbon steel blade is snapping cleanly at each segment after first use?
Press the snap end cap against a hard surface; each 23/64 in wide segment should break off cleanly, exposing a fresh edge without bending the remaining blade.
Does the box include replacement blades or only the 402L09 knife with its fitted carbon steel blade?
The package contains the snap-off utility knife with one fitted carbon steel blade; replacement blades are sold separately.
