Features

Boride sharpening stones are used for sharpening knives on Edge Pro sharpeners. Boride offers a wide range of stones with different performance values and different rates of wear. Boride stones are made of aluminum oxide, with the exception of CS-HD series stones, which are made of silicon carbide.

Q & A

• What is the difference between Boride and stock Edge Pro stones?

  There is no difference. Edge Pro stones are Boride 150 x 25 x 3 mm (6" x 1" x ⅛") branded as Edge Pro. Boride offers a wide variety of series and sizes, while Edge Pro offers a limited assortment. We buy sharpening stones from Boride and mount the stones to blanks. That's exactly what Edge Pro company does. The difference is we keep the names of the original sharpening stones in the names of the finished products.

• Can I use Boride stones and stock Edge Pro stones simultaneously?

  Yes, but you must use a thickness compensator because stock Edge Pro stones are 3 mm thick, while the Boride stones we offer are 6 mm thick. It's highly recommended to own a thickness compensator because the ability to use sharpening stones of different thicknesses allows for a high level of flexibility.

• What if I buy Boride stones 3mm thick to keep all my collection uniform?

  This is possible but not recommended as a long-term solution. The 6 mm thickness is becoming a community standard for Edge Pro sharpening stones. If you keep your entire collection 3 mm thick, you will not be able to use many good stones. You will also have to purchase 3 mm stones more often than 6 mm stones due to their shorter life cycle.

• 5 sharpening stones are too many for me. What should I buy?

  Consider buying Ruby 150, T2 400 and PC 1200. These 3 stones are the best Boride stones for sharpening knives.

• Can I buy one CS-HD and use it to sharpen all my knives? If it's okay for hard steel, it should be even better for soft steel, right?

  No, we do not recommend this. CS-HD will wear extremely fast when used on soft steel, making CS-HD uneconomical for this kind of steel. If you own knives of both hard and soft steel, consider buying 2 sets of stones.

• Can I buy a sharpening stone without a blank?

  We don't sell sharpening stones without blanks.

• What are the pros and cons of 6 mm and 3 mm thicknesses for sharpening stones?

  All stones wear as they are used and thicker stones have longer life cycles as a result. However, it's easier to use thinner stones on Edge Pro sharpeners because of their lower weight. The 6 mm thickness offers a perfect balance between life cycle and weight, and has become the community standard for Edge Pro format sharpening stones When made of hard material, 3 mm stones are good as ultra-fine sharpening stones, for example alumina ceramic or natural stones.
