How to Tell If Sharpening Stone Is Oil or Water

When choosing a stone oil or water stone, you should know a few things. This page will explain how to tell if sharpening stone is oil or water. I will discuss various types of sharpening stones, their suitability for knives, and how to determine if they are properly installed on the machine’s surface.

You can tell by the smell. Sharpening stones should have a clean, fresh smell that’s not overpowering. Oil stones have a distinct odor from water stones, which usually have little or no smell. You can also place a drop on the stone and see if the mixture spreads. Oil will spread to all sides of the blade while the water stays in the middle, waiting to separate.

Generally speaking, water stones are the most versatile and tend to remove metal faster than oil stones. Oil stones can also be used with water, but solvents can be cleaned more easily. Water stones should be soaked for five to ten minutes before use, while oil stones can be used with or without lubrication, depending on personal preference.

What Is a Whetstone

how to tell if sharpening stone is oil or waterA whetstone is a stone used to sharpen knives, tools, and other edge tools.

Whetstones are made of different materials and come in various shapes and sizes. The most common whetstones are from water-based materials such as quartz and aluminum oxide. These stones are generally softer than oilstones, which are harder and more brittle.

Most whetstones have a coarse side (coarse grain) and a fine side (fine grain). The coarse side is used to grind down rough edges on blades or tools. On the other hand, the fine side is used to sharpen them.

Natural whetstones include the Japanese water stone (also called the synthetic Japanese whetstone) and Arkansas stone; synthetic whetstones include silicon carbide and diamond.

What Is an Oilstone

An oilstone is a stone that you use to sharpen knives and tools. They’re called oilstones because they must be periodically lubricated with oil to work correctly. 

The oil helps keep the metal particles from clumping together as you grind them down, making it possible to get a finer edge on your blades.

However there are many different types of oilstones, but they all work the same way: by being pressed against the blade at an angle until it reaches its sharpest point.

The main types of oilstones are:

  • Arkansas stones (smooth grits), which are made from silicon carbide and are used for removing chips from metal surfaces such as blades;
  • India stones (medium-fine grits), which are made from aluminum oxide and are good for honing blades that have already been sharpened on coarser stones;
  • Hard Arkansas stones (fine grits), which are made from silicon carbide and are used for finishing blades after they’ve been honed on medium-fine India stones; and
  • Soft Arkansas stones (extra-fine grits), which are made from silicon carbide and are used for grinding dull blades

What Are Whetstones Made Of

 Whetstones are made of natural sandstone, which is quarried worldwide. The grain size of whetstones can vary widely, depending on the manufacturer, but they typically range between 3000 and 8000 grit.

Whetstones are divided into two types: oilstones and Waterstones. Oilstones are made with a fine-grained mixture of clay, water, and oil; this mixture binds together to form a solid stone. 

Waterstones can be made with different rocks, including aluminum oxide or silicon carbide; these are harder than oilstones, so they don’t require as much maintenance and can be used with water or oil as a lubricant.

 Whetstones are made of a variety of materials, but the most common are:

  • Aluminum oxide (also called corundum) is the most commonly used material for whetstones. It’s inexpensive, durable, and easy to shape.
  • Silicon carbide is another common material for whetstones. It’s tough and resistant to wear but can be brittle if not properly shaped.
  • Natural minerals like garnet and amazonite are prized for their ability to hold an edge without being too hard on tools.

Oil Stone Vs Water Stone

Oil Stone Vs Water StoneWater stones are often used to sharpen kitchen knives and other household items, while oil stones are more commonly used to sharpen high-quality tools.

Oil stone 

Oiling a stone by applying oil to the surface of a whetstone or sharpening stone. It lubricates the stone’s surface and prevents it from becoming clogged with metal particles. The oil also helps cool the stone during use, making it last longer.

Oil stones are used for sharpening tools such as axes, hatchets, and other hand tools requiring sharpening. They are made from different types of sandstone and limestone, depending on what type you want to use for your project.

Oil stones don’t require any soaking.

Water stone

Water stones are used for sharpening knives and tools like chisels and plane blades. These stones are generally made from silicon carbide, aluminum oxide, or natural garnet, a type of silicate mineral that can be found naturally in some parts of the world.

Water stones also need to be lubricated with oil before each use. But, again, it is another thing that takes time and effort, and it’s something that many people forget to do when they’re in a rush.

How Long to Soak a Whetstone

How long to soak a whetstone depends on the type of stone you’re using, its size, and whether or not it’s been pre-soaked (and, if so, how long). Most whetstones should be soaked for at least 20 minutes before use.

Some whetstones are pre-soaked and ready to go right out of the package but may need some time to absorb water before being used. How long you soak your whetstone depends on the type of stone, your time, and your personal preferences.

Here are the different types of whetstones:

• Diamond stones: These are pre-soaked and ready for use. You can easily take them out of their packaging and start sharpening them.

• Natural Arkansas stones: These are also pre-soaked and ready for use. You can just take them out of their packaging and start sharpening them.

• Other natural stones: These may need to be soaked before use depending on how coarsely ground they are (a coarser grind means more surface area per volume). If this happens to your stone, I recommend soaking it for at least 30 minutes before using it.

How to Clean Sharpening Stone

How to Clean Sharpening StoneFirst, it’s important to note that each whetstone has its cleaning method. Some require just wiping with a damp cloth, while others require soaking in water or vinegar for several hours. To find out what will work with your stone, check the packaging or contact the manufacturer directly.

If you’re using an oil stone (like those made of Arkansas or Novaculite), you only need a little soap and water. Here’s how:

1. Put a little mild soap on a sponge or cloth and rub it onto the top and sides of your stone. It will eliminate any dirt or grime from years of use.

2. Rinse the stone with warm water until all traces of soap are gone from both sides of the stone (and from any crevices).

3. Dry it off with a towel if necessary you don’t want it sitting wet for long periods because that can cause rusting, and store it in an airtight container until the next time you need it.

How to Clean Diamond Sharpening Stone

How to Clean Diamond Sharpening StoneA diamond sharpening stone is used for keeping your knives sharp. Unfortunately, it’s also a great way to dull your knives if you don’t know how to clean and maintain them properly. Here’s what you need to do:

1. Cleaning with Water

The first thing that you need to do is let the stone soak in water for at least 5 minutes. After this, take out the stone and let it air dry completely before using it again. It will prevent rust from developing on your sharpening stone and protect its integrity for longer periods.

2. Cleaning with Oil

Suppose you prefer not to use water on your sharpening stone regularly; other options are also available, such as using mineral oil or vegetable oil instead of water when cleaning it off after use.

This method tends to be just as effective as water alone but may not yield as good overall results due to being less effective than water alone when used regularly over time.

Soft cloth and Water

1. Place the stone in the container of warm water and allow it to soak for five minutes.

2. Use the soft cloth to wipe down both sides of the stone, working from smaller grooves toward larger ones. If there are any stubborn spots or stains, use a toothbrush with soap or detergent and scrub them out gently.

3. Rinse off the soap with fresh water, then dry your stone completely with a fresh cloth before storing it away again.

Wet Dry Sharpening System

 A wet-dry sharpening system is a great tool in your garage or shop. It lets you sharpen your blades right at the job site, so you don’t waste time going back and forth between home and work.

Also, great if you’re working on an old car that needs its blade sharpened quickly or if you want to ensure your new lawn mower is ready for next season.

Wet-dry sharpening systems are easy to use: dip the blade into the water and run it through the sharpener. The water will keep it cool while sharpened, so there’s no need for special cooling agents like oil or wax.

And because these systems are designed specifically for wetting operations, they are made from materials like plastic or nylon that won’t corrode when exposed to moisture. They also have rubberized grips on their handles so they won’t slip out of your hands when wet.

Furthermore, the two main types of wet-dry systems are diamond stones and Arkansas stones; diamond stones use diamonds embedded into their surface, while Arkansas stones use regular abrasive material (typically silicon carbide).

Both types can be wet or dry depending on the pressure needed during sharpening (the less pressure needed, the better).


Aside from the guide above on how to tell if sharpening stone is oil or water, it’s very simple to tell if a sharpening stone is oil or water because most of them are labeled on their packaging. So if it says water or oil on the label, it’s most likely water or oil on the inside.
