Ardennes-Coticule
REF
Small natural stone for sharpening the inside of gouge cutting edge, with a rounded side and a 45° bevelled side.
These are recycled off-cuts. The shape will never be the same, but we propose two constants: the rounded side has a diameter of just over 5mm and the stone is just under 5cm long.
Its grain is between 8000 and 16000
Coticule sharpening:
This is always done with water. Simply moisten the surface of the Coticule: the stone must not be immersed. During sharpening, the surface of the Coticule releases garnets. The more garnets it releases, the more abrasive the paste.
Advice:
Coticule is a non-porous stone, so it cannot become clogged.
Only use water and not oil when sharpening. Oil should only be applied to porous stones to prevent iron particles from depositing in the pores.
Longevity of the stone: the longevity of the stone depends on how it is used. The more intense the use, the quicker the stone will wear out. Generally speaking, stones last 20 years with normal use.
