The Procat double-sided whetstone is specially designed for sharpening knives. Its two different grits, K150 and K320, allow for both pre-sharpening and blade finishing with the same tool. The coarser K150 side is well suited for pre-sharpening worn and damaged blades, while the finer K320 side is intended for finishing and fine-tuning the blade.
The design of the whetstone ensures a comfortable and secure grip during sharpening. Its compact size makes it easy to store and transport, which is especially useful for professionals and hobbyists who need a sharpening tool even when working on the move.
Made from high-quality materials, the whetstone ensures a long service life and consistent sharpening results. The durability of the stone ensures that it retains its shape and roughness for a long time, making it a cost-effective choice for sharpening tools.
Intended use:
Knife sharpening: The Procat whetstone is ideal for sharpening a variety of knives. The coarser K150 side effectively removes larger irregularities and damage to the steel, while the finer K320 side finishes the blade, making it extremely sharp and ready to use. This two-step sharpening process ensures that your knives stay sharp and usable for a long time.
Knife sharpening: Kitchen knives and other cutting tools benefit from regular sharpening with a Procat whetstone. The coarser side repairs any damage and unevenness to the blade, while the finer side gives the knife the sharpness needed for precise cutting. This improves cooking efficiency and safety.

Procat Grinding Stone 2 grits K150 / K320 user manual:
Preparation: Carefully clean the blade to be sharpened from dirt and grease.
Wetting the stone: Wet the whetstone with water or sharpening oil. This reduces friction and prevents metal particles from accumulating on the surface of the stone.
Pre-sharpening: Start sharpening on the coarser K150 side. Place the blade at about a 20 degree angle to the stone and drag it evenly across the stone, keeping the angle the same throughout the movement. Repeat this on both sides of the blade until the desired shape and sharpness is achieved.
Finishing: Turn the stone to the finer K320 side and repeat the sharpening process. This will remove any scratches left from the pre-grinding and give the blade its final sharpness.
Cleaning: Wipe the blade and whetstone clean with a damp cloth to remove metal particles and excess oil or water.
How to choose the right whetstone:
There are several factors that affect the sharpening result and user experience when choosing a whetstone. Different whetstones are suitable for different purposes, and their characteristics, such as grit rating, material and wetting requirements, should be considered before making a purchase decision. Below is a comprehensive guide to choosing the right whetstone.
1. Grindstone grit rating (Grit value)
The most important characteristic of a whetstone is its grit, which is determined by the grit value (K). The lower the number, the coarser the stone. The choice of grit depends on how dull or damaged the blade is and the desired result.
Coarse grinding stones (K80–K200)
Suitable for pre-sharpening very dull or damaged blades.
Quickly removes large irregularities and corrects the shape of the blade.
They do not leave the blade ready for use, but require a finer finish.
Medium-coarse grinding stones (K200–K800)
Multi-purpose stone grades that are suitable for both pre-grinding and basic finishing.
A good choice for general sharpening and regular maintenance.
Suitable for most knives and penknives.
Fine grinding stones (K1000–K3000)
Used for finishing blades and achieving a precise cutting edge.
Especially suitable for kitchen knives and razors.
Leaves the blade very smooth and ready to use.
Very fine grinding stones (K4000+)
Intended for finishing and polishing.
Often used in razors and surgical instruments.
Leaves the blade with an almost mirror finish.
When choosing the grit of a whetstone, it is worth considering that many stones have two different grits on different sides. This allows for both pre-grinding and finishing with one stone.
2. Grindstone material
Different grindstone materials affect how quickly the stone sharpens metal and how long it lasts. Below are the most common materials and their pros and cons.
Synthetic grinding stones (aluminum oxide, silicon carbide)
Extremely wear-resistant and wears evenly.
Fast sanding and easy maintenance.
Suitable for most blade materials.
Natural whetstones (Arkansas, Belgian bluestone, Japanese waterstones)
They provide a softer and more subtle sanding feel.
May wear unevenly, requiring leveling.
Particularly suitable for fine grinding and finishing.
Diamond grinding stones
Very durable and effective.
Suitable for hard and wear-resistant metal alloys.
More expensive than other options.
3. Wetting the grindstone: Water or oil?
Grinding stones can be divided into two main types based on their wetting requirements:
Water whetstones
Used with water, which makes grinding smoother and prevents the stone from clogging.
Easy to clean and maintain.
A popular option for sharpening kitchen knives and hand tools.
Oil grinding stones
Requires special sharpening oil to function optimally.
Can last longer than water stones.
Well suited for grinding metal and wood tools.
Some stones have the option to use both water and oil, but it is recommended to follow the manufacturer's instructions.
4. Purpose of the grindstone
Different whetstones are suitable for different tools and applications. When choosing, it is worth considering what tool you are sharpening.
Knives and penknives
Medium and fine grinding stones (K150–K1000) are best suited.
Double-sided stones, with both a rough and a fine side, are a good choice.
Chisels and axes
Often require a coarser stone (K80–K200) for initial grinding.
Finishing can be done with a medium-grit stone.
Razors and surgical instruments
Very fine stones (K3000–K8000) are recommended.
Finishing is very important for these tools.
Scissors
Medium and fine stones provide the best sharpening results.
The smooth grinding surface helps keep the scissors blades straight.
5. Size and shape of the grindstone
The size of a whetstone affects its use and storage.
Small grindstones (less than 15 cm long)
Best suited for pocket knives and small tools.
Easily transportable, but not suitable for large blades.
Medium-sized whetstones (15–25 cm long)
A good all-purpose size for kitchen knives and penknives.
They offer enough surface area for sharpening without being too large to handle.
Large grindstones (over 25 cm long)
Suitable for large knives, such as chef's knives and machetes.
They offer a longer grinding area, making sharpening easier.
The shape of a whetstone can also affect its suitability for different tools:
Flat stones: Best for general use and knife sharpening.
Round and curved stones: Especially useful for curved blades, such as scythes.
Diamond files and sharpening bars: Used for precision sharpening, such as scissors and hook blades.
