Boride PC recommended stones set

The Boride PC (Polisher's Choice) abrasive stone series represents high-quality sharpening stones manufactured using a unique technology with aluminum oxide. This series falls under the category of "Specialty Polishing Stones" in the Boride classifier. According to usage recommendations, Boride PC stones effectively work with carbon steels, stainless steels, and high-alloy steels (including high-speed steels). Thus, this stone series is designed to handle practically all types of steels used in the knife industry, ensuring consistently high-quality results with each.

The PC series stones are characterized by a soft structural bond, allowing for efficient processing of hard steels. The Boride PC series has a broad steel processing range, and the softness of the bond, rated on Boride's 5-point scale (a value of 3 for the PC series), is another advantage. Additionally, the Boride PC stone series utilizes a complex composite abrasive grain, where fine abrasive particles are combined into larger conglomerates. This ensures high metal removal performance on stones with various grit sizes while maintaining the cleanliness of the surface.

The recommended Boride PC set includes 5 grits:

• 150,
• 220,
• 400,
• 600,
• 1200.

Stone characteristics:

• Size: 160x25x9 mm (6" x 1" x ⅓")
• Working surface size: 152x25x6 mm (6" x 1" x ¼")
• Weight: 83 g (1.6 ounces)
• Abrasive: aluminum oxide

The Boride PC series stones feature an impregnated composition, meaning a solid filler with a unique formula is used in the inter-abrasive space. This component prevents clogging during sharpening and reduces the consumption of cutting fluid (coolant) during use. When sharpening with Boride PC stones, it is recommended to use lubricant. The best choices for this purpose are Boride PREMIUM STONING OIL or BORI-LUBE 10, which align best with the composition of the inter-abrasive impregnation in Boride PC stones.
