A razor knife is a small, handheld cutting tool that uses a thin, replaceable blade for precise cuts. It’s commonly called a utility knife or box cutter and is handy for opening cartons, trimming carpet or vinyl, scoring drywall, and crafting.

• Common styles: Retractable, folding, snap-off, and blade scrapers.
• Helpful features: Quick-change blades, safety locks, ergonomic grips, and onboard blade storage.
• Use tips: Retract or lock the blade when not cutting and work on a stable surface.

Walmart offers a range of options online and in-store, with pickup and delivery available in many areas.

Yes—most folks use “razor knife,” “utility knife,” and “box cutter” interchangeably. The names refer to compact cutters that hold sharp, replaceable blades for everyday tasks.

• Razor knife/utility knife: General-purpose cutter for cardboard, plastic, and light materials.
• Box cutter: Often a retractable style designed for breaking down cartons.
• Variations: Folding models (pocket-friendly), retractable sliders (quick and safe), snap-off blades (fresh edge by snapping), and scrapers (for adhesives and paint).

When browsing at Walmart, choose the style that fits your tasks and comfort. Features like quick-change mechanisms and blade storage can make everyday cutting more convenient.

For frequent box work, many shoppers prefer retractable utility cutters because they’re quick to deploy and easy to retract between cuts.

• Retractable: Simple slider control and safety lock; good for steady, repetitive tasks.
• Folding: Compact to carry; the blade is protected when folded.
• Snap-off: Multiple segments provide a fresh edge without a full blade swap.
• Extras: Features like a twine/strap cutter and onboard blade storage can help in shipping/receiving areas.

At Walmart, you’ll find all three styles. Pick the grip and mechanism you’re most comfortable using and consider blade availability for easy replacements.

Blade changes are usually quick, but it’s smart to take a moment for safety.

1. Retract the blade fully and engage the safety lock if your tool has one.
2. Open the blade hatch or use the quick-change release per the tool’s instructions.
3. Carefully remove the used blade and insert the new one in the correct orientation.
4. Close the mechanism and test the slide or lock before cutting.
5. Dispose of used blades in a puncture-resistant container.

Consider cut-resistant gloves and a clear workspace. Designs vary, so checking the included manual can help. These steps can reduce risk, but results depend on your tool and setup.

Most utility cutters use either standard trapezoid blades or 9–18 mm snap-off blades. Fit depends on your tool’s mechanism and blade size.

• Check: The tool’s packaging or markings for blade type/size.
• Match: Trapezoid blades for many retractable/folding styles; snap-off strips for segmented cutters.
• Storage: Some handles include space for spares, so carrying extras is easy.
• Convenience: Walmart offers multipacks online and in-store, with pickup and delivery in many areas.

If you’re unsure, compare the shape and dimensions of your current blade to what’s listed in the product details to find a compatible option.
