## Long description

Replacement Upholstery Knife Blades Silver 100 x 18 x 0.5 mm SK5 are precision straight rectangular blades designed for cutting fabrics, leather, foam and similar materials used in upholstery, sewing and craft work. Made from SK5 high-carbon steel, these thin 0.5 mm blades provide clean, accurate cuts and are sized to fit common utility and upholstery knife handles. The pack contains multiple identical blades prepared for quick replacement and consistent blade geometry for repeatable trimming tasks.
Advantages
These Silver replacement blades combine the hardness and edge retention of SK5 steel with a slim 0.5 mm profile that reduces drag through textile and foam layers. The standard 100 x 18 mm dimensions make them compatible with many upholstery and utility knife holders, enabling fast blade changes and stable fitting. The straight rectangular shape supports precise, straight cuts and controlled trimming without unnecessary material waste.
Suitable for
Cutting upholstery fabric and leather
Trimming foam, batting and cushions
Precision cutting in sewing, tailoring and craft projects
Replacement blades for compatible utility and upholstery knives
Key specifications
Blade material: SK5 high-carbon steel
Blade dimensions: 100 mm length × 18 mm width × 0.5 mm thickness
Shape: straight rectangular cutting edge
Intended use: manual cutting and trimming of textiles, leather and foam
How to use
Install the replacement blade into a compatible upholstery or utility knife following the handle manufacturer's instructions, ensuring the blade is seated and secured before use. Make controlled, steady cuts with the knife at a consistent angle; the thin 0.5 mm blade is optimized for low-resistance trimming of fabric and foam. Replace the blade when you notice reduced cutting performance or burrs along the edge to maintain precise results and reduce the risk of snags.
Usage recommendations
For prolonged blade life, avoid cutting materials containing metal or abrasive fillers. Use a cutting mat or solid support under the workpiece to preserve edge sharpness and reduce the chance of damaging the blade. Store spare blades in their original pack or a protective sleeve and dispose of used blades in an appropriate sharps container.
