The 6000 grit is side splash and that's about it. Just add water every few passes. It certainly gives you a nice polished edge, but that side requires a bit more skill to master. Maintaining the angle is a bit more important, otherwise you will have some ruts in the stone, so go slow and try to feel it and don't go for speed.

It takes some time to sharpen all knives at their natural angle, but keeping them at that angle and sharp takes no time at all.

The handle of this sharpener features areas of rubber for added traction to help maintain a secure grip while sharpening with wet hands.

This is a best-in-class, easy-to-use sharpening product.

One side is red and the other is green. Red picks up a dull blade and sharpens it first. Maybe 5-6 passes per side. Then move on to the green to take sharpening to a new level with 3-5 passes per side. Almost like new. A dull knife takes about 3 minutes to sharpen. And sharpening the knife, using only the green side, takes about a minute.

Unless your blades are damaged or you want to reset the angle of a chamfer on your iron, this is probably the only sharpening tool you'll ever need.

While some may find this price to be high, remember that you are getting a large 3" x 8" double sided diamond sharpener.

Unlike natural stones, the polymer base does not deform either. It stays perfectly flat over time. And sharpening goes much faster. 10 hits on this stone is roughly equivalent to 50 hits on any cheap stone. Not only does it save time and energy, but it's also much easier to maintain a very consistent blade angle for 10 strokes than it is for 50.

This stone is large enough to accommodate even yourlarger kitchen knivesin one knife pass. A few passes (maybe 10-15 on each side, alternating 5 at a time) are enough to restore the paper cutting edge to your knives. That makes it bulkier for camping, but for the right tool at the right time, that's unbeatable.

DMT DuoSharp is very very fast, smooth, easy to use.

Don't try this with a serrated blade, it won't work, otherwise it's fine for most normal blade lengths.

Another important feature is the fact that the system is maintenance-free and can even be used dry.

This sharpening system is definitely worth the price. Highly recommended.

It seems to accumulate some kind of filings in the metal paste, as well as some abrasive, but it is a resistant stone.

If you have knives made from decent carbon steel, this is the most useful grit to use around the house.

It is a good bottom grain stone. The scratches it creates are even and not very deep. You can switch to 1000 grit easily and you won't have a problem.

Since it is low grain, you can expect it to wear down quickly. You'll notice wear after 10-15 uses, but once you've smoothed it out with a diamond plate, it's ready to use again.

It will easily reset blade angles, but with more effort and time than a coarse stone.

Types of sharpening stones

There are different types of sharpening stones available and we are going to discuss them.

(Video) The Last Knife Sharpening Video You Will Watch

1. Water stone/whetstone

This is the most common type of sharpening stones, also known as whetstones. Many professionals recommend these sharpening stones because they are very easy to use and also come in different sizes and grits. They only require water as a lubricant, which is why they are also called sharpening stones. You just need to soak it in water for 10 minutes and it is ready to use.

Some stones just need to be rubbed with a little water before use.

In addition to Japanese water sharpening stones, they are very cheaply priced,

They are very fast and require very little maintenance, but slower than diamond stones.

2. Oil stone

Oil stones are also another great way to sharpen your knives and other tools. These are traditionally western whetstones.

The oil is used as a lubricant and these types of sharpening stones come in fine, medium and coarse grit to finish and polish your knife.

Oilstones are made of novaculite, silicon carbide, and aluminum oxide.

This is a long lasting sharpening stone because aluminum oxide is a very hard material.

So you can use the oilstone much longer than a whetstone/whetstone.

3. Ceramic stone

This is another type of knife sharpening stone, but these types of stones require a high level of care and maintenance. Because they are very hard and break easily.

Ceramic stones are good for polishing your knife, not for very dull knives.

These stones do not require any kind of oil or water before use. These are best for ceramic knives or knives that have a very thin, flexible blade like fish fillet knives.

4. Diamond stone

If you have a good budget, we recommend that you choose a diamond stone for your knife. There are a few reasons why diamond stones are more expensive than others. Because it has a very special diamond nano-coating technology.

This is the fastest growing type of sharpening stone because these stones can sharpen your knife very quickly and require quite a bit of maintenance.

Because of these qualities, diamond stones are the favorite choice of many professional chefs and people who enjoy outdoor activities.

Grain, base and angle guides

grain range

The secret to the success of a sharpening stone lies in its grain. The grit is what makes your blade sharp, removing the metal from the blade as it is applied to the surface of the grit to produce a sharp new edge.

The grit ranges from 240 to 8000. When it comes to the grit range, the higher the number, the finer the grit.

  • Coarse grain: 200-800

  • Medium Grain: 800-1500

  • Fine grain: more than 1500

grain use


A good base will help prevent the stone from sliding across the surface as you sharpen the knife. Most bases are made of silicone rubber, plastic, bamboo, or wood. A rubber silicone base will ensure the stability of the stone. Plastic can be used near water, but bamboo and wood bases look nice but may not last long if they get wet.

angle guide

If you don't have enough sharpening experience, an angled fence helps hold and keep the knife blade at the correct angle for effective sharpening, which can also help prevent accidents.
