There are many options for whetstones; Two of the most popular are whetstones and diamond whetstones. There are obvious differences between them, mainly the method of production, the material of production, and the type of blade used to sharpen the knife.
Diamond stones have tiny diamond particles glued to the metal surface and don’t need a lubricant but will last much longer. At the same time, whetstones are made from natural stone, require oil or water as a lubricant during sharpening, and will eventually wear out.
Let’s start by looking at the diamond stones in more detail, and we will consider how they are made, what they are made from, and the practical pros and cons of these highly durable sharpening tools.
There are three primary ways that diamond stones are made. The first method utilizes a block of machined steel or aluminum upon which the diamond chips are integrated. While this produces the flattest surfaces, the cost of materials and manufacture is very high, so this is not a standard option for diamond stone production.
The second way involves impregnating diamond chips into a thin steel plate which is then glued to an aluminum block. The method used to cut the steel is essential as high-temperature laser cutters can deform the steel plate, resulting in more machining needed to correct the deformation.
This is often done using high-pressure presses to straighten the plates. In most cases, more straightforward steel-cutting methods offset costs and time in the manufacturing process.
The third way involves using flexible copper or plastic sheets impregnated with diamond chips and then glued to various backings depending on the customer’s requirements. One of the drawbacks of these flexible foils is that they can be easily damaged or cut when sharpening.
Diamond stones offer the user a great many advantages. While they are often more expensive than whetstones, one of their most apparent advantages is that they will outlast whetstones by some margin as they are tough and not quickly dulled or damaged.
Diamond stones are also excellent for people who need to sharpen tools and blades on the move as they remove the most material on each sharpening pass and sharpen faster and easier than the whetstones.
Diamond stones are great for hunters, outdoors people, and adventurers as they will not break or crack if dropped and can be used without oil or water to sharpen axes, hunting knives, and skinners to a sharp, practical edge.
There is a common misconception that diamond stones remain sharp throughout their lifetimes, but this is not the case.
If you feel the surface of a diamond stone when new, it will feel sharp, but after a while, this sharpness will become dulled, and the diamond stone will move into a medium sharpness stage. In this sense, diamond stones are more like sandpaper than whetstones as they are essentially an abrasive surface on a non-abrasive base.
As with sandpaper, it will gradually remove less and less material over time as wear and tear on the diamond particles takes effect. This would be particularly pronounced when the stone is used to sharpen or grind tough materials.
However, you need to remember that while there will be some surface deterioration, it will take years to notice this. Using a whetstone for the same purposes would result in the stone getting damaged far quicker than a diamond stone.
One tip here is to buy a diamond stone that has monocrystalline diamonds, as these will maintain sharpness in the medium sharpness stage for much longer than polycrystalline diamond stones.
Monocrystalline diamond stones maintain their shape and offer higher sharpening speeds as they don’t lose shape and offer more consistent and accurate sharpening.
Whetstones and diamond stones are both popular tools for sharpening knives and other edged tools. Each has its own advantages and characteristics. Here's a breakdown of the differences between them:
Made from natural or synthetic abrasive materials.
Natural stones (like Arkansas stones) and synthetic stones (like Japanese water stones or oil stones) are common.
Available in a wide range of grits, from very coarse to very fine.
Tend to wear down and need to be flattened periodically to maintain a flat surface.
Usually require water (water stones) or oil (oil stones) as a lubricant to carry away swarf (metal filings) and to reduce friction.
Some synthetic stones can be used dry, but lubrication is typically recommended.
Generally provides a smooth, polished edge.
The process can be slower compared to diamond stones, especially for harder steels.
Requires more skill and practice to achieve a consistent edge.
Needs regular flattening and maintenance to ensure effective sharpening.
Over time, the stone can become uneven and require re-flattening.
Made by embedding diamond particles on a metal plate.
Available in various grit levels, often indicated by a number (e.g., 300, 600, 1200).
Extremely hard and durable, as diamonds are the hardest natural material.
Maintain their flatness over time and do not need to be flattened.
Can be used dry or with water; oil is generally not recommended.
Easier to clean and maintain compared to whetstones.
Provides very fast cutting action, especially useful for hard or high-carbon steels.
Can produce a slightly rougher finish compared to whetstones, though higher grit diamond stones can achieve a fine edge.
More forgiving and easier for beginners to use effectively.
Requires minimal maintenance.
Less prone to becoming uneven or clogged compared to whetstones.
Whetstones are ideal for those who want to achieve a highly polished edge and are willing to invest the time and effort into maintaining the stones. They are also great for traditionalists and those sharpening softer steels.
Diamond Stones are perfect for those who want a fast, efficient sharpening process with minimal maintenance. They are particularly effective for harder steels and for users who prefer a straightforward sharpening experience without the need for frequent flattening.
