Factors to consider when buying a knife sharpening stone

A list of the best knife sharpening stones is not enough to help you make the right choice. For this, we want to recommend some basic features that you should take into consideration before purchasing.

1. Type

There are mainly four types on the market:

  • Water stones: they are the most common, the easiest to find and according to experts they are also the best, especially because they can be found in different grains. Simply dip them in the water for a few minutes before using them.
  • Oil stones: with a pass of oil on the surface of the stone before use, the residues that are created during the process are easily removed. Like water, they are quite durable and depend on the hardness of the stone.
  • Ceramic stones: they are the most durable since they are made with very hard particles and do not need oils or water. They need more accurate maintenance and greater delicacy in use.
  • Diamond stones: without a doubt, they are the best stones for sharpening knives on the market, but since they are made of diamond they are also the most expensive. Resistant and reliable, they will last you a lifetime.

2. Type of grain

The type of grain defines the natural sharpening stages through which the blades pass. A coarse grain begins, which is the one that removes the old thread and brings out the new blade. The medium grain is the one used to give a first cleaning and finishing after passing the coarse grain (this step can be skipped by going directly to the next). While the fine grain is the last step to clean the blade in the best way and remove any type of particle.

3. Grain gradation

There is a gradation of the grain levels, depending on the blade you want to sharpen with the stone. These are the main ones:

  • > 300: this type of grain is able to eliminate a very high number of particles. Precisely for this reason it is used only sporadically and is highly not recommended for beginners.
  • 300-400: very coarse and perfect grain for a stone that is used to restore the edge to a blunt knife. Eliminate a large number of particles. Again it is not suitable for beginners.
  • 1000: excellent basic grain, suitable for everyone, even the most inexperienced, will help you give new life to your kitchen knives.
  • 1200-2000: very similar to the previous one, it is the best for Japanese knives, which are more delicate than other types of blades. The more you go up with the level of gradation, the fewer particles of the blades are consumed.
  • 3000: it is a medium-grain that is used to finish the blade and ensure a longer duration for sharpening. To avoid the formation of cracks, it is very useful to wet the surface before use, obviously always following the manufacturer’s instructions.
  • 5000-6000: a gradation suitable for everyone, it is perfect for a final finish. Also for these, it is advisable to always follow the manufacturer’s instructions.
  • 8000: this is the best grain for finishing. It is very fine and will help you give your instruments an almost mirror shine. This type of gradation must not be immersed in any liquid unless recommended by the specific manual.

4. Safety

This is a factor to be taken absolutely into consideration. Handling blades are dangerous, especially if they have just been sharpened. This is why sometimes there are non-slip bases on the stones, such as bamboo or silicone, for better and safer adherence to the work table and to avoid any dangerous slippage.
