What are sharpening stones?

  Diamond sharpening stones for top quality  

Sharpening stones are tools used to sharpen or hone the edge of a blade, or similar sharp-edged tool. They are most commonly used with steel tools. Sharpening stones are often referred to as whetstones, water stones, or oil stones, although these names can also refer to specific types of sharpening stones designed for particular uses.


These stones are available in a variety of shapes, sizes, and materials, and come with various levels of abrasion. Their level of abrasion is relative to the size the grit particles on its surface. Coarse stones have relatively large particles and lower grit numbers. Fine stones have much smaller particles and high grit numbers. Sharpening stone’s grit numbers refer to the number of particles per square centimetre, so, the larger the grit number, the finer the stone.

Diamond stones are actually thin metal plates with tiny industrial diamonds fixed to their face, rather than being real stones. These diamonds are harder than any other type of sharpening stone, natural or synthetic. Diamond stones often have perforated surfaces that capture the waste metal as the tool is sharpened. The main advantages of using diamonds stones over other sharpening stones are that they are particularly quick at sharpening and they retain their flat surface much more easily than stones, which can curve or hollow over time due to the sharpening process.

Monocrystalline diamonds


Trend aim to produce the highest quality products, which is why they use monocrystalline diamonds for their sharpening stones. Monocrystalline diamonds are single structures which will not break, giving them an exceptional lifespan. These shatter-resistant diamonds are bonded onto a precision ground surface, set in nickel, and electroplated. This process locks the diamonds in place through a complex manufacturing process. Many other brands use polycrystalline diamonds, these are a cheaper alternative which is a fragmented structure that will wear down much faster as they are prone to breaking with use. Also, these diamonds are not electroplated, instead, they are adhered to a surface with a glue that can quickly degenerate and cause the stone to fail. This is why diamond stones vary so much in quality and price.

Many of the Trend diamond stones are double-sided and have two grit sizes in a single stone. This allows for one stone to complete coarse sharpening on with side and a finer finish with the other. The monocrystalline diamond surface is continuous to prevent smaller tools from snagging. Trend diamond sharpeners utilise complex manufacturing processes for their diamond stones to provide the following advantages:
