Utility Knife

What is it?

The utility knife, or box cutter, has a retractable, replaceable blade for scoring and cutting drywall, cardboard, plastic, and thin material. Its small blade and secure grip make precise cuts easy.

What is it used for?

• Scoring and snapping drywall
• Cutting sheet material and packing
• Trimming thin plastic and shim stock

How to choose

Choose a knife with a sturdy, non-slip handle and easy blade change. A retractable or fixed blade depends on your reach habit.

Anatomy

Understanding the parts of a utility knife helps you use, maintain, and buy it with confidence.

• Body: the main working portion of the tool
• Working end: the part that contacts the material
• Handle: the part you grip for control and leverage

Materials & construction

Quality utility knifes are made from hardened, heat-treated steel (often chrome-vanadium or high-carbon) chosen for strength, edge retention, and resistance to wear and corrosion.

Safety & maintenance

• Inspect the tool before use and replace any that are worn or damaged
• Use the right tool for the job and apply controlled force
• Store tools clean and dry to prevent corrosion
• Wear appropriate eye protection for the work
