There are many different materials for general purpose sharpening operations. The most popular choices include diamonds, ceramics, Waterstones, and oilstones. Diamond stones are the hardest and most durable solution for heavy-duty use.

Ceramic tiles are also tough but can be more challenging than other options. Water stones are softer than diamond or ceramic stones, making them easier to use but wear out sooner. Oil stones are the traditional abrasive sharpening stone and the most common, having been about for decades.

What Factors Should You Consider When Choosing A Sharpening Stone Set?

1. What type of tools will you be sharpening? The stone’s diamond surface makes sharpening efficient. For restoring a sharp edge or flattening the backs of plane blades, start with 300 grit. Choose in the range of 300, 600 and 1200 grit to cover most workshop needs.

2. Consider the dimensions. To choose the right size, determine the type of knife or tool and the angle at which it will be worked. From the small 3/4″ x 2″ Eze-lap 5 piece offering for touching up router bits to big bench plates.

3. Check the abrasion. Grit refers to the abrasive ability, with higher grades providing sharper blades. Finer microns are recommended for things that require a fine edge. Also, consider the type of metal your working with and its hardness.

4. Think about the brand and warranty. Some brands, like DMT and Smith’s, have built their whole business on sharpening tools. Most of these stones have a lifetime warranty, so you can be sure they will last.

5. It’s crucial to analyse the stone’s pricing, specs, and quality. Also, consider the type of stone and how it will be employed.

What Are The Different Types Of Diamond Bench Stones?

Two main types of diamond bench stones, either continuous or interrupted diamond surface. But each has its own advantages and disadvantages. The broken surface of the interrupted sort makes it challenging to hone point tools. On the other hand, continuous diamond surface coatings tend to be more costly.

They have also come a long way since the first versions. Now available in all sorts of shapes and sizes for different purposes.

There are micronized monocrystalline diamonds are uniformly sized (MCD) and polycrystalline diamonds (PCD). PCD is a composite with multiple surfaces bonded together; they tend to be cheaper. MCD is grown as a single piece with many surfaces. It is electroplated, which gives them a longer lifespan and will not break. With proper care, their exceptional scratch pattern, durability, and performance, they will last 10 to 20 years. MCD Sharpening is faster and cleaner than other methods for better efficiency.

Care And Maintenance For Combination Diamond Stones?

To maintain and make sure your diamond stone will last, you need to keep it clean. You can use them dry, but it is recommended to use a lubricant. To avoid damaging the stone, avoid overheating it or applying excessive pressure. Unlike others, there is no need to soak, flatten, or oil the stone before use.

Water is OK for lubrication though it may cause filings to rust if not cleaned and dried off properly. Better to use Windex or a lapping fluid though Krud Kutter is highly rated on woodworking forums.
