The PDT Premium Silver CBN Bench Stone is a professional large-format sharpening stone designed for users who demand fast cutting speed, excellent edge control, and long-term durability during freehand sharpening.

Manufactured by PDTools Superabrasives, this bench stone uses premium CBN abrasive combined with an advanced vitrified-metal bond, delivering aggressive material removal while maintaining stable abrasive performance throughout the sharpening process.

The vitrified-metal bond structure offers several key advantages:

• Fast and efficient cutting action
• Excellent wear resistance
• Stable sharpening feel
• Reduced loading during use
• Consistent scratch pattern
• High sharpening performance on both soft and hard steels

The available grit progression from #160 to #3000 allows the stone to cover multiple sharpening stages:

Compared to traditional water stones, the PDT Premium Silver CBN Bench Stone provides significantly longer service life, improved dimensional stability, and more predictable sharpening performance, especially when working with modern high-hardness steels.

Its solid steel blank construction adds rigidity and stability during sharpening, helping maintain precise control and even pressure distribution across the entire blade.
