How Sharpening Stones Work

Japanese Sharpening Stone Via pinterest

You know how a sandpaper works, right? Well, a sharpening stone works just the same – it works like a sandpaper in polishing metals. In place of the scrubbing motion of a sandpaper, however, metal blades need to pass over the stone in a slicing manner to sharpen them.

Here are some facts about sharpening stones:

  • Those with coarse grits can cut through metal faster – and therefore sharpen knives faster as well. Those with fine grits are mainly used for polishing and finishing touches.
  • There are soft and hard types of sharpening stones. The soft types can sharpen and cut faster than the hard types as new abrasive materials are revealed when the surfaces of a sharpening stone begin to wear out.
  • Lubricants are needed when using sharpening stones as debris from metals can hinder the cutting process. Oil or water can be used as lubricants (this will depend on the type of stone).

Types of Sharpening Stones

This section will discuss the 4 basic types of sharpening stones.

Water Stones

There are 2 types of water stones – natural and synthetic. Japanese water stones fall under the natural category, and this type of sharpening stone is quite expensive. The synthetic or unnatural stones are less expensive.

Since water stones are soft, they can wear out and become uneven faster. This doesn’t mean that they’re already ruined, however, as the surfaces of sharpening stones can be flattened again. Using another sharpening stone can easily fix the problem – and a Diamond sharpening stone can be used for this purpose. Click here to watch a video on how to flatten a sharpening stone.

Oil Stones

Oil stones are called as such because they need oil as the lubricant when sharpening knives and other cutting tools. These sharpening stones come in different grades, so you can choose from a course, medium, and fine grits. Your choice, of course, will depend on your goal and what you’re trying to achieve in sharpening your tools.

Ceramic Stones

Ceramic sharpening stones are named as such because they are made from ceramic powder combined with Aluminum oxide. Because of its composition, little to no lubricant is needed when using this type of knife sharpener.

Diamond Hones

Industrial-grade diamonds (not those used in jewelry) are used in a diamond honing stone. While it’s also a type of sharpening stone, the diamonds are actually attached to a plastic or metal plate.

As diamonds are hard, this type of sharpener can cut and sharpen metal blades very fast. A diamond knife sharpener is also more durable than regular sharpening stones. So, as can be expected, this is also the most expensive type of stone sharpener.

The use of lubricant is not needed in a diamond stone knife sharpener. You see, there are holes on the surface of the plates – those are enough to keep metal debris from hindering the sharpening process.

Grit Selection

There are 3 types of sharpening stone grits – each one is described below.

  • Coarse Grits – These usually carry 400, 600, and 800 grits. Course grits are able to cut through metal quickly – that’s why they are best used on dull and damaged blades.
  • Medium Grits – These are used to polish and finish off work after using a course grit sharpener. The grit level for medium grits is 1,000 to 2,000. As a 2,000-grit sharpener can already be considered fine, this can produce a very sharp blade when used as a finisher.
  • Fine Grits – Grits with 5,000 to 8,000 grades fall under the fine grits category. Such fineness is useful in sharpening and polishing hard types of blades.
  • Note: A really thorough sharpening procedure involves the use of course, medium and fine grits (in that order).

How to Use a Sharpening Stone

The process of using a sharpening stone to repair and sharpen cutting tools involves the following steps:

  • Step 1 – Selecting the proper coarseness of grits. You need to use a course grit sharpening stone to work on very dull or damaged blades. Medium to fine grits can work for slightly blunt blades and tools that only need minor touch-ups. Really fine grits are used for polishing and really sharpening the edges of blades.
  • Step 2 – Application of Lubricant (if needed). Floating swarf (or metal debris) will hinder proper sharpening of blades – that’s why oil or water is used in some types of sharpening stones.
  • Step 3 – Selecting the Angle. This is an important part of sharpening blades as the wrong angle can either ruin a blade or cause uneven sharpening. Ideally, the angle should be anywhere from 10 to 30 degrees – so, aim for a 20-degree angle to maintain proper balance.
  • Step 4 – Sharpening the Blade. Once you have the right angle positioned, start sharpening the blade by making a slicing motion over the sharpening stone. Perform this action on both sides of the blade – and for best results, sharpen both sides alternately.

  • Don’t store wet sharpening stones as they can get moldy. Allow them to air dry for a long time as the insides can still be wet even when the outside portion is already dry.
  • Clean your sharpening stone after use as debris from cut metal blades can remain on the surface of the stone. You can do this by washing it with water and mild soap and using a brush to totally get rid of metal particles
