Ardennes coticule

Belgian Blue whetstones are created from a 480 million year old sedimentary rock only found in one location in the world. A tonne of this rock is required to make each stone. These stones have been produced in Lierneux since 1625. Then with the advent of synthetic whetstones, production of natural stones declined. In 1982 the mine closed. By the 90's, however, there was an understanding that Belgian natural stones actually outperform synthetic ones. Maurice Celis and his son Rob re-opened the mine. Ardennes Coticule was formed.

TWO STONES IN ONE

The Belgian Blue consists of around 25% garnet crystals bonded with mica. The garnets are dodecahedron in shape, have a diameter of 5 to 15 microns. In a slurry they penetrate 1 to 3 microns into the metal to be sharpened, creating a #4000 grit edge. Their ideal geometric shape (obtuse angles polish the metal) and the large numbers of these garnets means the blade is sharpened very quickly and extremely finely. No other whetstone can match it.

With the slurry washed off, the embedded garnets stick up out of the surface by around half their diameter, or less. The shallower scratches produced by this finer surface are equivalent to approx. #12000 grit and replace the need for a leather strop.

A fine edge

For knives already sharpened with a medium stone, use the Belgian Blue to quickly create a fine edge of around #4000 grit. This is our recommended ideal edge – it is a little more durable than a #12000 edge due to having β€˜microserrations’. TOG kitchen knives are supplied with a #3000 edge. There is no need to soak the Belgian Blue. Splash some water on the surface then rub the little slurry stone in circles to create a paste / slurry. This speeds up the process. The slurry contains garnets which do the sharpening. Do not use a honing rod afterwards.

STROPPING

To polish or β€œstrop” your knife and produce the sharpest edge possible, wash the slurry off under the tap. Continue to sharpen on the clean Belgian Blue, but use lighter pressure to avoid creating a slurry. This will refine the edge further and produce a β€˜shaving sharp’ edge.

Hold the knife at a couple of degrees greater angle than before to ensure you’re working the very furthest point of the cutting edge. Use 10 to 15 strokes on each side of the blade. The edge produced is perfect for sushi or wherever you wish to get the cleanest cut possible.

    The stone is excellent, it has put a razors edge on my nakiri. It comes in a very nice wooden box complete with slurry stone and honing guides. You can feel the quality in the stone. I have purchased many items from Bert and his team and my only regret is that I did not find them years ago

    I hesitated to buy the Belgian Blue whetstone thinking that the 320 and 1000 grit stones with the honing rod would suffice- but I have to admit that it is bringing me great joy to use and my knives are much sharper.
