Proper maintenance and storage of Durham-Duplex blades is essential to ensure safety and maximise blade lifespan. Here are a few key tips:

Clean after use: Remove any debris, product residue, or moisture after each use. For industrial settings, follow the appropriate cleaning protocol depending on the material being cut (especially in food or medical industries).

Dry thoroughly: Ensure the blades are completely dry before storage to prevent corrosion or rusting—especially important for carbon steel blades.

Store safely: Use the original packaging or a designated dry, secure container. For safety knives, always retract the blade after use.

Regular inspection: Periodically check for signs of wear, dullness, or damage. Replace blades at the first signs of reduced performance to maintain precision and avoid machine stress or product damage.

Durham-Duplex also offers blade handling tools and dispensers to improve safe usage in industrial environments.
