Overview

The Westcott E-84020 00 Utility Knife Replacement Blades are a 10-pack of 18mm metal blades built to fit specific Westcott snap-off utility knives. Designed for models E-84009 00, E-84019 00, E-84022 00, and E-84023 00, these blades slide directly into the knife body for a secure, precise fit. The 18mm width is the standard large-format size commonly used for heavier cutting tasks such as cardboard, packaging materials, drywall, and general workshop applications.

Each blade is constructed from durable metal to maintain its cutting edge across multiple uses. Having a 10-pack on hand means you can snap off a dulled segment or swap in a fresh blade without interrupting your work. These are purpose-made replacements for the listed Westcott models, so compatibility with other brands or knife designs is not guaranteed.
