FAQ

what is Diamond Sharpening Stone Credit Card？

A diamond sharpening stone credit card is a small, portable sharpener that can fit in a pocket or wallet. It's made of a hard, flat, abrasive surface created by coating stainless steel with tiny industrial grade diamonds. Diamond sharpening stone credit cards can be used to sharpen a variety of tools, including knives, saw blades, small flat-bladed screwdrivers, and garden tools.

When choosing a diamond sharpening stone credit card, it's important to consider the quality and grit of the stone.

Some things to look for include:

Thickness

Some stones are not very thick and can flex, while others are wider and more precise

Surface

A continual surface is better than one with holes or gaps, which can feel lumpy and snag on tools

Here are some diamond sharpening stone credit cards to consider:

What is a diamond sharpening card?

A high quality stainless steel card is coated on one side with very small industrial grade diamonds to create a very hard, flat yet abrasive sharpening surface.

Can you wear out a diamond sharpening stone?

If diamond stones are properly maintained, meaning they are kept clean and stored dry, they can last a long time. For those that use stones on a daily basis and maintain them properly, the diamond will likely last years. For those that use them regularly, it's likely the stone will last from ten to twenty years.

What is a diamond sharpening stone used for?

Can be used for sharpening TC, HSS and PM steels, which are difficult or impossible to work using other types of stone. The stones mostly keep their original shape, unlike other stones that wear with use and must be periodically re-flattened. They can also be used as flattening blocks for Japanese water stones.

How long will a diamond sharpener last?

If you use your sharpener to sharpen your kitchen knives every so often, chances are your sharpener will last ten or more years. Some of our customers report their HUAYIDA sharpeners are still performing after twenty years of service!

What grit is a diamond sharpening stone?

For larger surface areas or to flatten the back of chisels and planes, it is best to use a 600 or even 1200 grit diamond sharpening stone.
