EXPERT KNOWLEDGE BELGIAN COTICULE WHETSTONES
The quarrying of Belgian coticule whetstones in the Ardennes dates back to Roman times. Even then, the value of this unique natural stone, also known as coticule, which was formed from volcanic ash around 480 million years ago, was recognised. The greyish-yellow sedimentary rock contains fine garnet crystals, which enable a special sharpening effect. During sharpening, these fine garnets are released from the rock and combine with water and metal abrasion to form an abrasive paste. This paste ensures an exceptional combination of effective material removal and fine polish - a globally rare property that makes the Belgian coticule whetones so special.
Production and dismantling
Around 1500 kg of rock has to be quarried to produce 1 kg of Belgian coticule whetstones. Only the finest yellow layers of the rock are suitable for sharpening and are therefore glued onto slate slabs to be cut into so-called bench stones or chunks. This elaborate process is reflected in the quality and price of Belgian coticule whetstones, but also gives this natural stone its special character.
Quality of natural stone
The Belgian coticule whetstones, together with the Arkansas stone, have been synonymous with high-quality sharpening stones for decades. However, as it is a natural product, fluctuations in quality can occur, particularly because resources are limited. This can lead to the tried and tested Grinding stones becoming rarer and more expensive in the future. Japanese water stones are a possible alternative.
Advantages and disadvantages of Belgian coticule whetstones
Advantages:
- Fine removal combined with fast polishing: This sharpening stone offers an excellent combination of efficiency and precision. The fine garnets only remove a minimal amount of material, which ensures smooth processing and a mirror-smooth polish at the same time.
- Durability: They are extremely durable and wear slowly due to their hardness, making them a long-term investment.
- Natural sharpening feel: Sharpening with natural stones such as the Belgian coticule whetstones offers an unrivalled sharpening experience that many craftsmen and knife lovers appreciate.
- Universally applicable: This grinding stone is suitable for many different types of cutting tools, from kitchen knives to hand tools.
Disadvantages:
- High price: As it is a rare natural product and the quarrying process is complex, Belgian coticule whetstones are among the more expensive grinding stones on the market.
- Fluctuating quality: As a natural product, the properties can vary from stone to stone.
- Slower material removal: Although Belgian coticule whetstones provide a fine polish, removal can be slower than with artificial stones or diamond stones, especially when a lot of material needs to be removed. The grit of Belgian coticule whetstones is 6000-8000.
- Maintenance: The Belgian coticule whetstone needs to be moistened regularly to work optimally and requires some patience and skill to use.
Tips for use
- Preparation: Before use, the Belgian coticule whetstones should be immersed in water for a few minutes. Unlike water stones, however, the Grinding stones do not need to be permanently in the water, but only slightly moistened.
- Sharpening: Sharpening is done in slow, steady movements with light pressure. The resulting grinding sludge of water and dissolved garnet crystals is essential for the sharpening result. The longer you sharpen, the finer the polish on the blade.
- Care: After sharpening, the grinding stones should be thoroughly rinsed with water and stored in a dry place to prevent cracking.
Variants
The blue Belgian coticule whetstones are a variant of the famous Belgian natural stone. It consists of a fine quartzite rock that - similar to the yellow Belgian coticule whetones - is embedded in a clay mineral matrix. The difference lies in the colour and the fineness of the abrasive grain: the blue Belgian coticule whetstones have a slightly coarser grit, around 4000, than the yellow one and are therefore somewhat faster at removing material.
Belgian coticule whetstones - who are they suitable for?
They are particularly suitable for lovers of handmade knives and tools who want to maintain their cutting tools to a high standard.
However, for everyday use or when a faster sharpening result is required, artificial grinding stones or diamond stones may be the better choice.
Conclusion: Belgian coticule whetstones - a grindstone for connoisseurs
The Belgian coticule whetstone is an exceptional natural stone that impresses with its unique sharpening properties. It combines fast sharpening with a fine polish and is particularly durable. Despite its higher price and somewhat higher maintenance requirements, it is an indispensable tool for many craftsmen and knife enthusiasts that cannot be compared with any artificial alternative. Anyone looking for maximum precision and long-lasting sharpness will not regret investing in a Belgian coticule whetstones.
