Clean the knife regularly to remove dust and debris that can affect the blade change mechanism. Wipe the handle with a dry cloth to maintain grip quality. Store the knife in a dry place to prevent rust or corrosion.

Frequently Asked Questions
What materials can a heavy duty utility knife cut?
A heavy duty utility knife can cut through materials like cardboard, plastic, drywall, rope, vinyl, leather, and rubber. The specific blade type may optimize it for certain materials but general blades handle most common packaging and construction needs.
