Besides, they offer a bench to sit the plate in so you can operate much more easily. The bench elevates the plate, keeps it non-slip so you get your job done precisely.

Why Diamond Sharpening Stone?

Incredibly flat

You would not believe until you have one and use them for a certain time. That’s why we say “incredibly”.

There is not enough time for us to test how much sharpening jobs need to be made to hollow the piece of stones. But in testing other sharpening stones or tools, hollowing out happens only after quite a few weeks.

At least, diamond stones will be still in good condition for longer use.

Fast sharpening 

As we know, the diamond is the hardest material found on earth. Therefore, whatever metal your knives are made of, sharpening with diamonds will be done pretty fast.

It’s no doubt why people apply this product in industrial sharpening work.

Long-lasting

And, as the toughest material on earth, it’s not easy to worn out stones surfaced with diamond, is it?

Diamond sharpening stones are costly. But it’s worth spending because you won’t have to buy renew brand one in the upcoming years. Would be it fair enough?

What Types Do We Have?

Depending on the density of diamonds on the surface, we will have different types of sharpening. Not alone, we also have to consider sizes, accessories, thickness and so on.

Let’s take a closer look!

Non-continuous Diamond

The name explains itself. You’ll have a piece of stones but with fewer small diamonds on the sharpening surface. 

You cannot determine spots with or without diamond by eyes but touching it, you’ll feel the non-continuous fillings.

The point here is when you lead the blade on top, swarf gets caught on tiny spaces. 

With these holes, sharpening will happen faster even with rusted tools, even with edge creation jobs.

The non-continuous diamond surface created the most popular stones for sharpening because almost every user can work on it. It’s easy and effective.

Continuous Diamond

Little holes are effective to catch sawft, as well as points. Therefore, with tools like pins or needles- things with tiny points, we have to work on a complete flat diamond surface.

Here comes the continuous diamond sharpening stone.

Besides, depending on the quality of the diamond also, sharpening stones will be classified in price and uses.

Mono-crystalline

Mono-crystalline diamond is also called synthetic single crystalline (SCD) with its structure forming under high pressure.

Thanks to the strict producing process, these artificial diamond are pure and therefore, super hard to crack.

With SCD, you can perform heavy-duty sharpening tools, including edge creations, rust removing and so on.

Poly-crystalline

Polycrystalline is made of attaching monocrystals. Therefore, it keeps the toughness not completely perfectly unbreakable.

Polycrystalline is cheaper and effective for common sharpening works on all types of metals.

Which size should I get?

best diamond sharpening stones - diamond sharpening stone size

People usually ignore this feature. They focus on looking for the best quality sharpening surface then bring home a small piece to handle a sword or vice versa.

We have to tell, size is important. You can work a knife through an 8-inch stone but is it necessary to pay more?

On the other hand, you cannot sharpen a big blade on an average 6-inch surface, can you?

So, whatever you choose, consider the size as the last step. We have some measurements:

  • Four, six and eight inches are three common sizes for sharpening stones in consideration of daily tools, for example, chief knives or scissors. 
  • With more specific tools in bigger sizes, you might have to look for more than an 8-inch piece.
  • Besides, the length is more important than the wide. That means you should pick one with a longer length in the same area. It’s because you will save more useless space in the middle and sharpening always happens on the edges.

Conclusions – Your Best Diamond Sharpening Stone?

DMT is always the best name to call for diamond sharpening stones. However, among those, what we impressed the most is the WM8EF-WB for both price and quality.

We supposed that everyone will bear in mind certain perspectives on their ideal sharpening stones, based on uses, budget, and quality.

We can’t tell you the above seven items are the best for everyone. It’s impossible to find perfection under the world’s opinion. However, getting to know this article means shortcutting a lot of your choice. I hope that you will not have to window-shop all day long!
