When your workflow involves high-volume prep or heavy-duty butchery, a standard 8-inch stone simply doesn't offer the surface area needed for efficiency. The Norton 12-inch Crystolon Benchstone (Model JUM3) is the industry's answer for maintaining large-format cutlery. Built from premium Silicon Carbide, this stone is specifically engineered for speed. Unlike aluminum oxide stones which prioritize a smooth feel, Crystolon is fast-cutting and aggressive, making it the superior choice for repairing chipped edges or resetting a primary bevel on dull blades. This stone features a dual-surface design that covers the two most critical stages of sharpening. The coarse 120-grit side is your 'reset' button, capable of grinding away nicks and straightening rolled edges with minimal strokes. Once the geometry is restored, flipping to the 320-grit fine side allows you to refine the edge to a professional working finish. Because of its massive 11.5-inch length, you can maintain a consistent angle through the entire pull of a long scimitar or breaking knife, a feat nearly impossible on smaller stones. Whether you are a high-volume line cook or a home enthusiast with a collection of heavy German steel, this stone provides the stability and abrasive power to keep your tools at peak performance without the need for hours of labor.

Restore Industrial Sharpening Speed with the Genuine Norton JM6 Medium Stone In high-volume commercial environments, the Norton IM313 system is the standard for maintaining kitchen cutlery. However, even the most durable stones eventually wear or glaze over. This Medium Crystolon Replacement Stone (MPN: JM6) is the exact factory specification required to bring your sharpening station back to peak efficiency. Constructed from premium silicon carbide, the Crystolon material is prized by professional sharpeners for its aggressive cutting speed. Unlike aluminum oxide stones, these silicon carbide crystals fracture during use, constantly exposing sharp new edges to the steel. This makes the medium grit stone the 'workhorse' of the IM313 unit—perfect for knives that have lost their keen edge but don't yet require a full coarse-grit regrind. Whether you are a professional butcher processing hundreds of pounds of protein or a chef in a high-pressure line environment, this stone ensures you spend less time at the sharpening station and more time at the board. Designed to be submerged in the IM313 oil reservoir, it remains lubricated and ready for immediate use, preventing the heat friction that can ruin a blade's temper. Learn More

When your commercial kitchen or butcher shop relies on the Norton IM313 Multi-Stone system, the Coarse Crystolon stone (JM3) is your first line of defense against dull, damaged, or rolled edges. Manufactured by Norton, the world leader in abrasives, this replacement stone is engineered specifically for the 11.5-inch multi-stone rotating case. Crafted from premium silicon carbide, the Crystolon material is prized by professional sharpeners for its aggressive, fast-cutting nature. Unlike aluminum oxide stones which prioritize finish, this coarse-grit abrasive excels at rapid metal removal. This makes it the indispensable tool for 'thinning' a blade that has grown too thick at the edge or grinding out significant nicks after a heavy shift. Because it is an oilstone, it remains porous and resists loading when used with genuine Norton sharpening oil, ensuring that every stroke remains as effective as the first. Whether you are maintaining a fleet of house knives or restoring a chef's favorite carbon steel scimitar, this stone provides the foundational geometry required before moving to medium and fine finishing stages.

Professional-Grade Lubrication for a Frictionless Edge Sharpening is a game of heat and friction management. Without the correct lubricant, even the highest-quality sharpening stone will eventually 'glaze'—a process where microscopic metal particles, known as swarf, become embedded in the stone's pores, rendering it useless. Norton 16 oz. Sharpening Stone Lubricant is engineered specifically to prevent this failure, ensuring your India or Crystolon stones remain aggressive and effective for years. The Science of Swarf Suspension This highly refined mineral oil is formulated with a specific viscosity that lifts metal filings off the stone’s surface during the sharpening stroke. By keeping these particles in suspension, the oil prevents them from clogging the abrasive grit. Unlike generic oils or lower-grade lubricants, this Norton formula is processed to meet strict United States Pharmacopoeia (USP) standards. This means it is entirely food-safe, a non-negotiable requirement for professional chefs, butchers, and home cooks who sharpen their tools in the same environment where they prep food. Why Professionals Choose Norton In high-volume environments like butcher shops or industrial kitchens, speed and hygiene are paramount. This oil does not cake, thicken, or turn rancid over time. It remains fluid, allowing for easy cleanup with a simple wipe. Whether you are performing a heavy repair on a coarse Crystolon stone or finishing a delicate edge on a Fine India oil stone, this lubricant provides the thermal stability needed to prevent localized heat buildup, which can temper the steel and ruin a blade’s hardness. Made in the USA, it represents the gold standard for traditional oil-stone maintenance. Learn More
