Knife Blades

Knife blades are replaceable cutting edges used with a compatible handle or independently, depending on the task. They cut a wide range of materials including paper, card, plasterboard, foam, plastic piping, hoses and sheet materials, and are typically manufactured from stainless or carbon steel for strength and snap resistance.

RS Australia stocks knife blades, cutter blades and utility knife blades in a range of shapes, profiles, blade formats and steel grades, including options from RS PRO. Browse the full range and get fast nationwide delivery on every order.

Types of Knife Blades

The right knife blade depends on the material being cut and the tool it pairs with. RS stocks a complete range of cutting knife blades to cover trade, industrial and DIY applications, from general-purpose flat blades to specialist profiles for flooring and precision work.

Utility Knife Blades

Utility knife blades are the standard replaceable blade for box cutters and general-purpose utility knives. Available in flat and snap-off formats, stainless steel utility knife blades and heavy duty knife blades are widely used across packaging, construction and warehouse environments where frequent blade changes are needed. When working with these tools, a good pair of cut-resistant work gloves is recommended.

Cutter Blades

Cutter blades are designed for scoring and cutting through plastic tubing, hoses and similar materials. A flat knife blade format is common here, offering controlled scoring without the risk of overcut. Heavy duty knife blades in this category are built to maintain a sharp edge under repeated industrial use.

Hooked Blades

Hooked blades feature a curved cutting edge suited to flooring, roofing and sheet material work. The hook profile pulls material into the cut rather than pushing through it, making these cutting knife blades particularly effective on floor coverings, vinyl and plastic sheeting.

Concave Knife Blades

Concave knife blades have an inward-curving edge that produces a clean, controlled cut on soft or flexible materials. These are a common choice for gasket cutting, packaging and insulation work where a flat knife blade would be harder to control.

Scalpel & Trimming Blades

Scalpel and trimming blades deliver precision cutting for fine detail work in craft, hobby, electronics and medical applications. These steel knife blades are available in a range of tip profiles to suit different cutting angles and material thicknesses.

Applications of Knife Blades

Knife blades, cutter blades and utility knife blades are used across a broad range of trades, industries and home applications. The blade shape and steel grade required will depend on the material being cut and the frequency of use.

Trade & Construction Cutting

On construction sites, heavy duty knife blades are used daily for cutting plasterboard, insulation, membrane, plastic piping and building wrap. A stainless steel knife blade or carbon steel flat knife blade holds its edge well across these demanding materials. When sanding or preparing wall surfaces as part of a fit-out, knife blades are often used alongside other finishing tools for scoring and trimming.

Packaging & Warehouse Use

Warehouse and logistics teams rely on utility knife blades and cutter blades for opening cartons, cutting strapping and trimming packaging materials. Snap-off blade formats are popular here for quick in-field replacement without tools. Heavy duty knife blades in this setting need to hold a reliable edge through high-volume daily use.

Flooring & Sheet Materials

Hooked and concave knife blades are the standard choice for flooring installers cutting vinyl, carpet, rubber sheeting and laminates. A stainless steel utility knife blade or heavy duty knife blade in the right profile reduces the effort required to score and cut through sheet materials cleanly.

Craft, Hobby & Home DIY

At the lighter end of the range, scalpel blades and trimming knife blades are used for model making, card craft, stencilling and precision cutting on paper, foam board and thin plastics. A steel knife blade in a fine-point profile gives the control needed for detail work that a larger cutting knife blade cannot provide.
