What To Consider When Shopping For The Best Sharpening Stone?
There is no need to fret over choosing a sharpening stone. With our helpful guide at hand, it should not be difficult at all.
We will break down some of the things you should consider when searching for the best sharpening stone so that you can have a good sense of what to look for.
You have a selection of different materials, grits, and sizes at your disposal. Our guide should help you choose the ones that best suit your needs.
So, without any further ado, these are the considerations when choosing a sharpening stone:
There are sharpening stones made of different materials. These materials have different properties and can thus differ in their grit range or lifespan. You should pay close attention to the material of the sharpening stone you plan to buy and make sure you will benefit from its characteristics.
Natural Sharpening Stones
Natural sharpening stones are, by definition, far more expensive than man-made whetstones. But the question is, are they worth it?
They definitely have a range of valuable properties and can produce a much finer and sharper edge compared to the majority of man-made sharpening stone materials.
There are a plethora of natural materials that are worthy of your attention.
- Novaculite: Novaculite is a common natural material used for sharpening stones. It is often referred to as “Arkansas stone.” It is very tough and provides an excellent finish to any blade. In fact, novaculite will maybe surprise you with how fast it can sharpen even the dullest blade.
- Siliciclastic Clay Sediment: If you want an impressive high-performance, try a natural sharpening stone made of siliciclastic clay sediment. It is a soft & smooth material and thus provides a superbly smooth finish too. The siliciclastic clay sediment sharpening stones are also known as “Japanese Water Stones.” They are expensive and hard to find. Unfortunately, being soft, these stones do not last very long.
- Belgian Bluestone: As far as the sharpening experience and finish are concerned, Belgian Bluestone sits somewhere in between novaculite and siliciclastic clay sediment. It is relatively expensive as well, mostly due to the costly mining process, but it will provide you with a balanced, effective sharpening approach to prove its worth.
Man-made Sharpening Stones
The aforementioned silicon carbide and aluminum oxide can be cut as natural stone but are sometimes man-made too. Mane-made versions cost less.
- Diamond Sharpening Stones: Diamond sharpening stones are made of tiny fragments of industrial-grade diamond attached to metal or plastic plates. Diamonds are the hardest material, and consequently, the sharpening stones made from them last the longest. They sharpen the blades faster than any alternative material too. Of course, you have to break your wallet to own a diamond sharpening stone. Still, if you can afford one, go for it!
2. Lubricating Method
Sharpening stones are very similar to sandpaper. When you sharpen a blade, you remove small particles of metal as well as particles of the stone you use. These particles remain on the surface of your sharpening stone and clog up its rough surface. You need to remove them in order to use the stone to sharpen some other blade. So how can you do that?
There are two options to prevent clogging and keep your stone in operating condition at all times. Some whetstones require oil, while some need only water to lubricate the stone before each use.
- Water Stones: Water stones typically need to be soaked with water before you use them. It means you’ll have to spend significant time well before you can start the sharpening itself. On the bright side, these stones are usually quite affordable and easy to maintain. They wear down more quickly, though.
- Oil Stones: Oil stones, as their name clearly indicates, require their surface to be coated in oil. You can lubricate the surface just before you start the sharpening process. Oil stones tend to wear unevenly and thus require laborious periodic flattening.
3. Portability vs. Efficiency (Pocket Stones vs. Bench Stones)
There are two types of blade sharpening stones: bench stones and pocket stones. What’s the difference?
- A bench stone is designed to lay flat on a surface. You can position it on a workbench or a countertop. Many bench stones are sold with an attached base made from plastic, silicone, or some type of wood, such as bamboo. They require minimal effort for smooth sharpening results. You can use them at home or in the workplace.
- Pocket stones are much smaller and thus far more portable. They allow you to sharpen a blade almost anywhere. Unfortunately, it is much harder to maintain a consistent angle & pressure when sharpening longer knives on a small surface.
Just like sandpaper has a sand count, each sharpening stone has a grit number. The higher the grit number, the finer the stone is since there are more grit particles in a specific area. In fact, the grit number shows how abrasive a whetstone is.
You should best use multiple different grit levels for your blades, which is why many sharpening stones are dual-sided. A dual-sided whetstone features a finer side and a coarser side.
- The coarser side with low grit allows you to make a good edge fast. It provides speed at the cost of precision and smoothness. For that, you will need the finer side.
- The finer side has a higher grit number and is ideally used after the coarser one. It will help you refine and polish the edge and make it the sharpest it can be.
In general, 400 grit is coarse. and 1,000 grit is fine. The best sharpening stone offers both of these and thus serves the majority of households well.
Interesting fact: Japanese Waterstones can have as much as 30,000 grit, and that is why Samurai swords are so sharp.
The best sharpening stone should have a sturdy base that will help prevent it from sliding around during the sharpening process. Most often the base is made from the following materials:
- Rubber Silicone
Even though bamboo and hardwood have the most elegant look, in terms of durability, a rubber silicone base is a better option. It guarantees the stability of the stone too. The plastic base is a good choice if you work around water, while bamboo and hardwood will get ruined sooner if they get wet constantly.
6. Angle Guide
An angle guide supports the blade at the proper angle for the most effective sharpening. Experienced users can do without it, but newbies should definitely rely on it for better results and accident prevention.
Oil stones are the cheapest option, especially if you opt for general-purpose ones. Arkansas and diamond stones are much more expensive but still quite cheap in comparison to Japanese sharpening stones that can cost as much as $600!
