India stones

India Stone Defined

India stones are manmade, unlike other sharpening stones. Aluminum and oxygen are chemically combined to form them. Stones like these are generally categorized as being between soft and hard. 


Color and Grit

There are three types of this stone: orange, tan, and brown. Their variation of colors adds to the product’s attractiveness in a way.

Shape and Size

The stones are rectangular. Their shape is not typical of most sharpening stones. However, round ones are also being manufactured but are less popular.

In terms of size, there is a range to choose from.


Grit levels are ranging from 100 to thousands. Stones with a lower grit level are coarser. In addition to sharpening very fast, low-grit stones also produce a rough finish.

The high grit level stones, on the other hand, have smooth surfaces. Your knives will have a very smooth, sharp finish with these stones.


With a score, around 150 is the coarse-grit India stone. This grit is highly coarse that sharpening a dull blade can be done easily.


Then, there is medium grit. These have a score of 240.


The fine ones have a score of 400. These are best for polishing tasks.



The product is manufactured in the United States by Norton. These stones are built sturdy and they will last even with constant use.


You can sharpen any type of blade on these stones. Types include knives, chisels, and scissors. More so, they can be used for both sharpening and polishing.


They are also very lightweight. This makes it possible for you to take them along with you wherever you go.


These stones cost a fraction of the price when compared to their natural counterparts. They are very cheap considering the quality of the product.

Sharpening Process

Step 1. Oiling

This tool is an oil stone. That means that it needs to be oiled before use. It is best to use an oil that is odorless and thin.

Step 2. Sharpening

Lay the India stone flat. During sharpening, you want to make sure the stone does not move. Now, with both hands, hold your knife and gently stroke it against your India stone.

Stroke slowly and gently as usual. Once you’ve stroked a few times, feel for a burr. When your knife appears with a burr, it becomes sharp and ready for use.

Note: Apply oil whenever you notice dryness on the stone during the sharpening process.

Step 3. Cleaning

To clean your stone, simply use a wet rag. After wiping, you can also get rid of excess oil by using a dry rag. It is important to clean the tool after use to ensure its longevity.

Do not forget to clean and dry the sharpened knife as well.

Final Verdict

In a nutshell, this sharpening stone is not your ordinary sharpener. They are durable and versatile but are inexpensive. Indeed, they are must-haves.
