Norton IM313 Medium Crystolon Replacement Stone JM6

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.
