Best Japanese Sharpening Stone To Keep Knives Razor Sharp

best japanese sharpening stone

Having dull knives in the kitchen could be classified as a catastrophe in its merit. However, aside from your culinary skills, kitchen knives could make or break your career as a chef. For instance, a sharp knife could be the difference between good sushi and meh! Sushi. Ingredients such as vegetables, poultry fish, and meats that need deboning, peeling, carving and mincing, will need ultra-sharp knives, which is where the best Japanese sharpening stone comes in.

Not all sharpening stones are the same, they all come in different grit sizes, and the grit sizes are given numbers. For instance, a higher number denotes a higher density which is what you'd use for a fine razor-sharp finish on the polished object's surface. FYI, the Japanese used natural stones as sharpening stones that were lubricated with water.

In this case, grit size refers to the smoothness that's produced when you sharpen a blunt knife by the sharpening stone. On the other hand, the grit size depends on certain factors, which include the shape of the particles, how a binder exposes each particle, how the larger particles are fractured into, the smaller ones by either polishing or grinding, the chemical composition of particles, the hardness of particles, etc.

Which Water Stone Is Best?

Japanese water stones come as either natural or synthetic, and either are known for their superior sharpening performance. This applies to Japanese tools and their Western equivalents as well. In this process, the loosely bonded abrasive grit is quickly washed out since it blunts during this sharpening process. It then exposes the new, sharp particles that can then work on the blade. Note that water stones are only lubricated using water; never use any oil.

Experienced knife makers formulate their knife sharpeners in different mixes and qualities. Therefore, most woodworkers will choose different stones from several different manufacturers to build a set of sharpening stones. However, once you get to know the stone's traits that work for you, you can find and settle that one supplier that provides all the stones you may need. At times this comes with its advantages. But then again, no one size fits all; each stone will fit some of your needs and preferential work style.

Which Knife Sharpener Stone Is Best for You?

a) Rough sharpening

This is when you need to remove chips along the rough edges or restore a really dull blade. In this case, you'll need stones that are between 120-400 grit.

b) Normal sharpening

In this case, you can use stones with a 700-2000 grit stone. However, taking off fine scratches and burrs that are left by the coarser stones or polishing the surface will need stones that are starting at 2000 grit. Technically, there's no upper limit, but stones above 10000 grit will practically not achieve such a measurable improvement on the edge. Interestingly, there is no Japanese measurement standard that's above 8000 grit. This means that, in the case where a stone is labeled as a fine grit stone, you simply have to take that manufacturer's word for it.

Tip:

If you have considerable experience with knife sharpening, then a finishing stone of 8000 grit would work best for you. However, if in doubt or are a beginner, then stones from 3000-6000 grit will still give you acceptable results.

Practically, if you also need to do a significant amount of knife sharpening, then you'll need at least 3 stones; one to rough-grind, one to do the sharpening and one to hone.

But if you occasionally sharpen blades and know that you won't need to remove the chip along the blade's edge, a combination stone will definitely suffice. The trade-off between the cost and speed will always determine the size that you choose. This means that the bigger the stone, the faster you can work and vice versa.

What Are The Types of Sharpening Tools?

a) Natural Whetstones 

These are naturally mined in different parts of the world. These are quite hard and will last you a long time. However, on the downside, natural Novaculite stones cut relatively slower and will usually need plenty of oil for lubrication.

On the other hand, Japanese whetstones are made from sedimentary rock, are softer and wear down much faster than the Novaculite stone. However, on the bright side, they cut better, so they'll sharpen quicker. These whetstones can only be used with water, which is why they're also known as Japanese water stones.

b) Synthetic Whetstones

Artificial/ synthetic whetstones offer a much better consistency than natural stone. This is because they're made using a bonded abrasive (aluminum oxide/silicon carbide) that's stuck together using a clay/glass/resin binding agent to become a block.

c) Diamond Plate Sharpening Stones

These are steel plates that are coated in small diamond pieces since diamond is literally the hardest mineral on Earth and comes in handy when sharpening items for sharp knives. These plates are durable but typically relatively pricier. Generally, diamond sharpening stones are not recommended for beginners and are often used to fix water stones that may have become uneven after some use.

What to Consider When Shopping for the Best Japanese Sharpening Stones?

A) What Size?

Different whetstones come in different sizes available. Small knives will need a smaller whetstone, while large knives or multiple knife sizes will need a larger whetstone for easier work. Keep in mind that a larger stone will cost you more than the smaller one.

B) What Grade?

These Japanese whetstones come in 3 grades and different grits, which include:

i) Rough

These come with the largest grit particles that are between 120- 140.

ii) Medium

Medium grit stone comes with grit between 700-3,000.

iii) Smooth

Smooth water stones come with a grade between 3,000-10,000

C) What Use?

How you use these stones for sharpening knives determine what stone you choose. For instance, a professional stone sharpening knife will be different from that of a hunting knife or that of a steak knife.

i) Chips and Dull Blades

For a dull knife with chips or blades that have become extremely dull, you use a rough stone.

ii) Regular Sharpening

For regular sharpening, you can use a stone that's between 700-3,000 grit.

iii) Buffing and Polishing

Since some rough Japanese sharpening stones can create some scratches on the surface of your blade, to get rid of them, use a smoother stone to buff and polish your blade.
