Things that matter while buying a Best Japanese Whetstone


There are different sizes available. That’s why you need to know which size will suit your job the most. Not all the sizes are working for a single type of blade. Every size works differently. Such as, if you want to sharpen some small kinds of blades then you will need a small whetstone for doing so. 

But if it’s about larger knives, then you must use a larger size of the whetstone. The larger whetstone will also be perfect for those who have different sizes of blades to sharpen. Though it will cost more than regular small stones it will be more useful if you buy a large water stone. 


There are several types of water stone you will find if you search for it. Though different types of water stones have a different method of use, you need to select that suitable one that you will need for your certain purpose. 

Such as, if you are looking for a stone for normal sharpening, then you will need those whetstones that are 700-2000 grit. On the other side, if you want stone for hard sharpening, then you will need a stone that is from 120-400 grit. Those grits will be highly recommended for rough sharpening. 

For polishing and give the blades a mirror-finish effect, you will need a stone that is minimum 2000 grit. And there’s a thing to let you know that there is no Japanese measurement above 8000. So, the highest grit is 8000. This grit will be the best for giving a mirror polish to the blades. 


Water stones are something that has to be stable when you are working with it. Several kinds of stones have a rubber and non-slip base. And those kinds of blades will keep things in place. That’s why you don’t have to look at the sharpener, and you can focus on the blade. 

Search for the non-slippery base but make sure you check the reviews whether this facility works well or not. You must take care of this thing before buying any knife sharpener. Otherwise, it can ruin the sharpening process and harm you too. 

Ease of use

Though it’s a tool of sharpening the blades easily, you need to know what the suitable stones are that will be easy to use. Different kinds of whetstones offer an easy-using facility. You have to check on those. 

But you should check the details and reviews too. The more the tool can be used easily, the more it will provide safety. That’s the reason you should be very careful about these things before buying them. 

Moreover, it’s important because if the product cannot be used properly, and you find difficulties then you must avoid using that tool. And to avoid buying these kinds of bad products, you must search it well, and then purchase. 


Every product has a certain price. And when you are going to buy any product, especially a water stone, then you must know what the price range should be. It is because buying anything with an illogical rate is not an option. 

Moreover, the price will be decided by the type of whetstone. Like, the single grit stones will be less in price. But the double-sided or multi grit stones will cost much. Those are quite expensive. But buying three different single grit stones will cost more than a multi-grit stone. That’s why we recommend you to buy a multi-grit stone to save money. 

That’s why you must research first and know what the suitable price for these water stones. Besides, set a budget of your own. And according to that budget, you will choose the product you like.
