Major types of Stones used for Sharpening Knives

The types of stones for sharpening you want is mostly personal, as is the kind of car you choose. Many citizens like Arkansas stones, others choose stones with diamonds for quick cleaning, and others like only water stones. We choose stones with diamonds. The bulk of clearer interactions use two to three forms of variations.

Sharpening pierces are called whetstones as well. The term ‘whetstone’ derives from the expression ‘what’ to sharpen. It goes despite the popular assumption that the name goes taken from the importance of having swallowed before use.

Five major types of stones

Oil Stones

For several years the oil stone is used to sharpen knives and equipment. This is a man-made stone with abrasive particles attached to a binding chemical. The petroleum name means that you need oil to lubricate the fuel until it is sharpened.

Oil stones are produced in two common materials:

Oxide Aluminum-This is one of the most popular choices in the field of handmade sharpening and sharpening of stones. Aluminum oxide stones, often orange or brown in color, are quick to cut and are ideal for cutting edges. You can consider the rough, medium, or great named stones. At 9 on the Mohs Hardness Scale, Aluminum Oxide is a very hard abrasive which makes it an excellent abrasive sharpening.

Silicon Carbide-The best types of stones for smashing. These stones are usually in a gross grit so that they are not as sharp as the edge of aluminum oxide or novaculite.

Silicon Carbide stones are 9-10 Mohs Harnessed and are good for sharpening in the beginning. As they can sharpen fast, you will find most people start to sharpen, then proceed to a stone of India before they finish with an Arkansas.

Oil stones have been used by many people as traditional Western stones. The stones are made of one of three materials (Novaculite, Aluminum Oxide, or Silicon Carbide) and are used to remove swarf oils.

types of stones


Natural pieds made of novaculite are the most common oil pillars. Such natural stones are collected and processed in Arkansas to create what we consider the stones of Arkan. These stones are classified into various density ranges and the finish of a stone on a rim. Washita is the coarsest of them. Nowadays, Washita is not that because it is very delicate. The higher categories are classified as Medium Arkansas (soft Arkansas), Strong Black, and Hard Translucent Arkansas (hard Arkansas). Such natural oil stones may create a polished surface but are more difficult to break than stones created by man. Hard Black Arkansas and Hard Translucent are less available and thus more expensive.

Indian Rock, created by Norton, is the most popular. The stones can be sliced easily and can also be rendered tools and knives with a fine edge. Such stones normally have a rating scheme that is good, medium, and coarse. Often these colored stones are brown and orange. Aluminum oxide (India Stones) is coarger when compared to the Arkansas stones. The Indian Stones are used to mask certain stages of coarseness in combination with Arkansas Stones.

 Silicon Carbide

Silicon Carbide is the fastest crushing oil blocks. Crystolon stones are also silicon carbide stones developed by Norton. They are also small, moderately, and simply numbered. Usually, they are colored brown. Although these stones do not yield such a fine edge as India or natural stones, the easy cut makes them ideal for initial sharpening. Because it is quick sharpening, using the Coarse Crystolon and working towards an Indian Stone and finishing with an Arkansas Stone is a common practice.

Good overall production and low price are the biggest assets of the oil block. The least expensive stones for purchase are a collection of India or Crystolon stones. Of the very productive Soft Arkansas to the expensive Hard Black and Translucent Arkansas Stones, the actual Arkansas Stones differ. Such stones are often very large, such that they rarely need to be flattened.

The major drawback of the oil stone is its slower rate of breaking. Oil stone is the slowest of the three main types of stones. It is also messier to clean up oil to remove the swarf than water.

Oil stone cost from $7 to $30 cheaply, with a standard 100-600 grain size.

Arkansas Stones

Arkansas Stones should be listed in their own right because the oil or gas can be used. It is also referred to as novaculite. A Latin word meaning “razor hammer” indicates the word Novaculite. Stones from the rock beds in the Ouachita Mountains of Arkansas were extracted since the early 1800s. These are carved into rectangular whetstones for sharpening of knives and instruments.

The Stone of Arkansas is the most confused about all abrasive sharpeners. Many of the online information is either defective or totally imprecise, but for a specific article, that subject is best saved. Our own knowledge and research are the information given below. Our own measurements in May 2019 are the specific gravity scores. Four stones of each type have been tested. The following values represent an average of the four samples.


The four classes of the Arkansas stones are Medium, Rough, Black, and Translucent.

Soft Arkansas-the coarsest stone of four is the Soft Arkansas stone. Typically, it is marbled in white, gray, black, orange or pink colors. The crop is 400-600. The plant. Weak Arkansas’ specific gravity is 2.22.

Hard Arkansas — The stone of Hard Arkansas is a good stone of oil. It is usually white and silver in color, but it can be bright orange or reddish in the whole block. The plant is 800-1000 equal. Hard Arkansas is 2.32 in specific gravity.

Black Arkansas – One of the finest of four is Black Arkansas. It is a very fine stone and colored in black or blue-black. There is a grit of 2000 grain in the Black Arkansas Block. Black Arkansas have 2,55 specific gravity.

Translucent Arkansas-The Translucent Stone is a fine stone as well. The hue may be very light gray, white or light pink colors that run through it occasionally. The grain is 3500-4000 equal. Transparent Arkansas has a peculiar gravity of 2.56.

Water Stones

Either natural or man-made (synthetic) stones can be water stones. The term water stone comes from the fact that these stones must be lubricated with water. For decades, natural waters have been exploited in Belgium and Japan and have a special place in sharpening stone culture and art.

As a result of the Roman Conquest, Belgian whetstone production began and the stones exported since the 17th century from Belgium. Belgian sharpening stones of two types; coticule and Blue Stone of Belgium (BBW). 8000 grains and 4000 grains of the Belgian Blue Rock. The world-famous Coticule.

Due to their many advantages, they also attracted great support. Unlike oil stones, both natural and plastic water stones are available. Just synthetic stones will be addressed, though, despite their availability.

In general, aluminum oxide is used for synthetic water penetration. This is the same abrasive substance that is used in stones from India. The difference between the two, however, is the binder that holds together the abrasives in the water stone. Water stones are softer because the old abrasively material is broken and replaced with fresh sharp materials, than Indian stones that promote fase cuttings.

Obviously, fast cutting is a water stone benefit. The other apparent advantage is that the swarm is separated from the stone with water instead of fire. The water pier is not fine, though. Wear also the stone faster with the softness that promotes rapid cutting. It tends to wear the stone evenly so that the surface is smooth again.

Following decades of quarrying, natural Japanese sharpening stones are rare, but still available today. Most of the piers are mined by straight razor users and knife enthusiasts near Kyoto, Japan, and are highly popular. Japanese whetstones vary in grains between 500 and 10,000, costing Nagura stone between $25 and $500 + for a large stone

Diamond Sharpening Stones

Diamond sharpening stones are the fastest growing form of sharpening stone and for many chefs and professionals are rapidly becoming the chosen stone. The diamond stones are made of the electric plastering of human-made diamonds. The nickel plating of the diamond particles gives them exceptional durability.

These operate extremely fast, are very robust, and easily sharpen everything, even high carbon, stainless steel, and ceramic cutters. They are also highly durable.

Strong and interrupted surface diamond sharpening stones can be found. Such stones quickly remove steel, require little maintenance and the average user is unlikely to wear a premium stone.

Ceramic Stones for Sharpening Knife

Ceramic sharpening stones were an early replacement of natural stones. Unfortunately, there are huge differences in the quality of ceramic stones, so be wary of them. Others are very soft and wash very fast, while at the other end of the continuum others are so heavy that they appear to glaze in a rush. Ceramic stones need to be well soaked for about 10 or more minutes to saturate the pores of the stone before use. Since all knife steels are different, we tend to find that ceramic stones tend to work better with some knives than others. There are no tough and fast rules, but we like Ao-ko ceramics and single-edged knives.


Although there are many types of sharpening stones, the above mentioned five are the most common. Make sure when you go out to buy your preferred stone, you check the authenticity because many counterfeit stones are being sold on the market.
