The Dexter Russell Industrial 4" Curved Notch Rubber Knife is a specialized, heavy-duty tool optimized for slicing through resilient materials with minimal effort, a hallmark of Dexter's industrial cutlery since 1818. Forged from high-carbon tool steel, its 4-inch by 1-inch curved blade features a strategic notch that wedges into tough substances, enabling smooth, gliding cuts without binding or tearing. The ergonomic hardwood handle fits comfortably in the hand for hours of fatigue-free use, secured with robust rivets for superior balance and durability. Measuring about 8 inches overall, this lightweight yet sturdy knife delivers exceptional edge retention and control, ideal for professionals in abrasive environments

Key Uses and Applications

This notched rubber knife is engineered for precision work on fibrous, elastic materials, outperforming standard blades in trades where clean separations are critical. Its primary applications include:

• Rubber and Gasket Processing: Excels at trimming hoses, seals, or belts in tire shops and automotive repair, with the notch allowing initial leverage for effortless full-length cuts on thick rubber without slippage.
• Insulation and Foam Fabrication: Ideal for scoring and trimming fiberglass, foam insulation, or weatherstripping in HVAC or construction, providing controlled access to curved or layered surfaces for waste-free results.
• Leather and Vinyl Trimming: Handles edging shoe soles, upholstery fabrics, or synthetic composites in cobbler or manufacturing workshops, where the curved profile ensures accurate, non-marring incisions.
• General Industrial Utility: Doubles for notching conveyor belts, packaging materials, or adhesives in maintenance tasks, offering versatility for technicians needing a reliable, single-tool solution.

For lasting performance, hand-wash immediately after use, dry thoroughly, apply a thin layer of mineral oil to the blade, and hone as needed; fine steel wool removes minor discoloration. A staple for pros in rubber-heavy industries, this knife earns praise for simplifying "tough cuts" that would otherwise require multiple tools.
