• Application fit: Thin film, carpet, drywall, plastic, foam board — each has ideal blade geometry.

Types of Utility Blades for Knife

Utility blades come in many shapes, sizes, and configurations. Let’s break down the common types you’ll encounter and their uses.

1. Standard Two-Notch Blades. These are classic utility blades with two notches that fit standard handles. They’re used in box cutters and general multi-purpose tools. Example: Excel Blades #92 series. Ideal for cutting cardboard, opening packaging, trimming light materials.

2. Straight Edge Utility Blades. These utility safe blades have a clean rectangular shape, good for making straight cuts through heavier materials. Example: Excel Blades #80 Straight. Use cases are for laminates, sheet plastics, veneers, carpet underlay.

3. Snap-Off Utility Blades. Segmented blades with multiple snap-off sections give you a fresh edge quickly without replacing the blade housing. Common sizes: 9 mm (with 13-point, 6-point segments) and 18 mm (8-point segments). Example: Excel Blades 18 mm 8-Point Snap Blade. Best for: high-volume cutting of cardboard, foam board, vinyl, signage, craft boards.

4. Specialty/Coated Utility Blades. These blades have special coatings (TiN, ZrN etc.) or unique geometries. Example: Excel Blades #92 TiN Coated HD. Use-cases for when cutting tougher materials (drywall, insulation, rope, glove leather), or for improved durability and lifespan in heavy-duty applications.

5. Mini / Hobby Utility Blades. Smaller or more precise micro utility blades aimed at creators, hobbyists, modelers. Example: Excel Blades Single-Edge Razor, #11, #96 micro blades. Used for detailed work in arts & crafts, model building, vinyl cutting, precision trimming.

6. Utility Knife & Blade Handles. While the blade is critical, the handle and knife itself matters too.

• Straight length examples: #80 Straight Blades Length 2.125" (≈ 54 mm). 
• Thickness variation: Heavy-duty blades may be ~0.024" thick (#20092). 

Choosing Size Based on Task

• Heavy duty: 18mm snap-off, coated blades, thicker steel.

FAQs - Utility Blades

Q: What’s the difference between a “utility blade” and a “box cutter blade”?
A: The terms often overlap. “Utility blade” refers to the detachable blade used in utility knives. A “box cutter blade” is usually a utility blade optimized for cutting cardboard/packaging. Functionally many are the same.

Q: Are coated blades worth the extra cost?
A: Yes, if you’re cutting tougher or abrasive materials. A coating like TiN (titanium nitride) reduces friction and wear, which extends blade life. Example: #92 TiN coated 2 Notch Utility Blades. 

Q: Can I use a hobby razor blade for heavy duty cutting?
A: Not recommended. Hobby blades are designed for light duty & precision tasks. Using them on heavy materials will dull them quickly and may be unsafe.

Q: When should I replace a utility blade?
A: Replace when you notice uneven cuts, increased resistance, or edge chipping. Snap-off blades allow refreshing the edge easily. Here's a guide on when to change your blades. 

Q: Are all utility blades the same quality?
A: No. But Excel Blades is U.S.-based (Paterson, NJ) and emphasizes “Made in USA”, high quality for blades inventory. 

Q: What blade size is best for a craft room versus a construction site?
A: For craft/precision: 9mm snap, #96 micro blades, straight edge small size. For construction: 18mm snap, heavy duty two-notch, coated blades.

Q: Can I use a utility knife for materials like carpet, linoleum, or vinyl?
A: Yes—choose a heavy duty blade (thicker steel, coated if needed), ensure the handle is stable, and adjust cut depth accordingly.
