Is water or oil required during the sharpening process?

Avoid using water during sharpening, as it may cause the iron filings on the stone's surface to rust. Testing shows minimal difference in sharpening performance between using oil and dry sharpening, so oil is not necessary.

After using the stone, dark areas appear on its surface. Does this mean the diamonds have worn off?

No, the dark areas are dried dirt from sharpening, not a sign of the diamonds wearing off. These marks don’t affect performance and can be left as is. For minor marks, use an eraser. For tough stains, clean with Bar Keepers Friend and air dry fully.

Should I use high pressure when sharpening with this diamond stone?

Avoid applying excessive pressure when sharpening, as it can accelerate wear on the diamond and shorten its lifespan. Instead, use light pressure to maximize the sharpening performance of the diamond particles.

How long does it last?

The lifespan depends on usage, the hardness of the materials being sharpened, and maintenance. With proper care, it can last many years, even for those sharpening 3 to 4 times a week. Regular cleaning and light pressure extend its durability.

What is the cause of the rust and how can I deal with it?

The base of this product is stainless steel and will not rust. Any rust is caused by iron filings left on the stone's surface that oxidize if not cleaned. Use Bar Keepers Friend powder to clean it and ensure the stone is fully air-dried.

How to clean the diamond stone?

To clean the stone, gently wipe the surface with a dry paper towel. If particles are clogged, use a rubber eraser or nylon brush to remove them. This will restore the stone to its original condition.

Great product.

I use this file to sharpen the teeth on my sawmill. It saves me hundreds of dollars over the year simply because I have better control rather than the electric sharpener. It well worth the money.

包丁研ぎ最高です。

飲食店で包丁がたくさんありますが、簡単に砥げました。早く知ってたらよかったです。先が変に曲がった包丁も簡単に形を整えることができました。あとは耐久性がどれくらいあるかです。

Small, convenient and always at hand.

Love this! Very handy to keep in your tool box where a oil-/ water stone may not fit. The two sided grits provide useful rough and smooth honing of bladed tools.
