The base that comes with this stone works well. In between the base and the stone is a silicone coating so that the stone never moves when you are sharpening a knife. The bevels also come in handy so that you can sharpen your knife with any angle.

This is an easy-to-use Waterstone that is easy to set up. All you need is water to help you sharpen; no oils or mess that comes with the experience.

Not as high grade as the previous stone from Sharp Pebble, but it may just be all you need for the kitchen, and it is much more affordable.

This is not a real problem if you don’t have a spare cloth, but some people might find the preparation time to be too long.

You will also soon realize that this stone is too coarse for knives that you own that are meant to stay fine, such as a sushi knife. With that considered, it’s a better idea to buy another Waterstone that comes in a grade that is higher than 1000.

Their appearance is similar, with a light blue grit of 1000 and a white grit of 6000. They are both 7.25 inches long, 2.25 inches wide and one-inch thick. They both have a bamboo base that is designed in the same way. It is like one company copied the other, albeit we are not sure which one judging by what we know.

They also can sharpen any kind of blades, thanks to their aluminum oxide materials. They can sharpen replica swords, scissors, axes, pocket knives and more. They are also easy to use with water, so no oil is ever needed or warranted.

So what is actually different about this Waterstone from Sharp Pebble’s Waterstone? Firstly, purchasing this stone gives to a 100-percent money back guarantee for a whole year. If you are not satisfied with your purchase, you can get a full refund.

The bad part about this stone is that once it is wet, the silicone bottom underneath the base can be quick to fail. If you are in the middle of using this stone, the base can budge with enough pressure exerted. This is not a good thing, as you will want your Waterstone to be completely still when sharpening your knives.

  • Can sharpen any kind of blade
  • plus
    Has two different grades to sharpen with
  • plus
    Comes with a base
  • plus

5. KING KW65 Whetstone with Plastic Base

KING KW65 Whetstone with Plastic Base

The King Japanese Waterstone has a nice, natural look to it. This too is a two-sided whetstone. On the tan grit, is a 6000 grade. On the brown side is a 1000 grade. A plastic border separates the two sides of the stone. This stone comes with a plastic base that is beveled.

This Waterstone is slightly bigger than the other Waterstones. On one hand, homeowner can enjoy bigger surfaces and edges to sharpen with. On the other hand, it might just be too big for your current counter space, shelf space and/or drawer space, and arrangements should be made in order to fit everything in your kitchen.

To use this Waterstone, submerge only the brown side of the stone. Do not soak the lighter side, otherwise it will crack and break. You can sharpen your kitchen knives and blades flawlessly, making this a very useful stone.

This is a rather simple Waterstone, but its quality is certainly questionable at best. This stone is made of ceramic, for one, which while still is a viable material for sharpening, it is not one that can last long or survive an aggressive stress test. We recommend to not buy one online, as it could crack or break during transportation. With that said, we aren’t sure where this stone is sold in stores. Perhaps as the seller what can be done to ensure this Japanese Waterstone a safe trip home.

Secondly, using this stone on a ceramic knife will sure to wear out the knife, rather than sharpen it. Like using a metal blade to cut metal, the life of the knife will certainly accelerate rather than extend.

Pros​​​​​

  • Has two different grades to sharpen with
  • plus
    Comes with a base
  • plus
    Has a great color scheme 

Cons

  • Made of ceramic

6. KnifePlanet Complete Knife Sharpening Stone Set

Pros​​​​​

  • plus
    Comes with a base

Some Important FAQ About Japanese Waterstone

If you still aren’t sure on which Japanese Waterstone to buy, here are some answers to questions that may be on your mind at this point.

What do the grit numbers mean?

Grit numbers measure the fineness of blade sharpening. The higher the number, the finer the blade that you need in order to sharpen it right. Grits can range from 100 to 8000.

For rough sharpening, either to restore a very dull blade or to repair an unusual chip, you should buy a stone that is from 120 to 400 grade. Normal and basic knife-sharpening calls for a stone that is in between 700 to 2000 grade.

Waterstones can also be used to remove scratches from knives as well. To remove small scratches left by a coarse Waterstone, use a Waterstone that is around 2000 grade.

There are stones that are made in 3000, 6000 and even 8000 grade, as stated before. To tell you the truth, these are all acceptable grades that deliver the same results in sharpening fine knives. 8000 grade Waterstones are more complicated to handle, so if you are inexperienced in sharpening knives with a Waterstone, we recommend a stone that is 3000 or 6000 grade.

If you sharpen knives sporadically, or only intend to sharpen them sporadically, a combination stone will be a good purchase for you. This stone has two halves of two different grades, such as one with a 1000 grade and one with 6000. You can first use the rough side to sharpen your knife, and then use the finer side to sharpen it even further.

Why are Waterstones better than oilstones?

The soft, abrasive particles of a Waterstone break off when you sharpen, repeatedly exposing sharp new edges. As you continue to sharpen, those severed crystals are reduced into smaller crystals. These broken off crystals blend with water that is on the stone’s surface, which creates a compound that polishes and refines knives.

The stone must be dried before you store it. Storing a wet Waterstone will result in a development of mold and/or mildew on or inside the stone.

In comparison to stones such as oilstones, there are hard, abrasive particles that these whetstones give off. Rather than breaking off and exposing new sharp crystals after use, these stones take a round shape and grow dull. Furthermore, metal and oil particles occupy the pores of the stone, and smooth out the surface of the stone, rendering them less and less effective with every use.

How much should I buy for a Waterstone?

Some Waterstones cost as low as 20 dollars, while others can cost as high as 80 dollars. While it can be tempting to buy the least expensive whetstone, they either can be only for coarse knives, or of subpar quality. Finer stones, which can be up to 8000 grade are usually the most expensive. Combination stones, such as the ones in this review, provide a coarse and fine side, and cost you around 25 to 50 dollars.

Final Verdict

There is one Japanese Waterstone that we recommend that you buy, and that is the Culinary Obsession : 2-Sided Knife Sharpener Set.

Aluminum oxide is arguably the best material for a whetstone that you can buy. With grits of 1000 and 6000, this stone offers you a wide range that can sharpen all kinds of knives. You can consider this an all-in-one Waterstone that can serve you well in the coming years.

This stone from Culinary Obsession is the only one that can give you a money back guarantee if you are not satisfied with your purchase and want it returned. This is guaranteed to be a quality stone, and if it isn’t, you are sure to get a replacement that is.
