CORUNDUM STONEMade of corundum with granulation 220 in different colours (beige, orange, white etc.), which doesn't change its application characteristics. This stone permits a fast removal of metal from the instruments, even if these are already very worn out. Use always before stones with finer granulation and never for final sharpening.
Application: dry or with water.
Cleaning: rub stone with sandpaper and water.

NATURAL STONE "Tiger" Quartz is the abrasive material most frequently occurring in nature, however only few natural stones indicate the correct relation between quartz and carbonate (bonding agents); a perfect equilibrium that the natural stones "Tiger" of our production achieve.
The natural characteristics of the stones are still emphasised by the use with water, which, reacting with the lime, removes it slightly, leaving the abrasive quartz granulates permanently exposed. All this allows a quick and perfect cleaning of the stone, whereby the abrasive characteristics are permanently maintained.
Quality of the natural stone "Tiger": High quartz content with homogeneous distribution of the sharp-edged quartz grains of only few tenths of a Micron, showing a high friction ability also after long use. This characteristics allow an easy, hygienic (without synthetic oils) and permanent use.
Cleaning: leave stone to soak in water an vinegar for about 12 hours.

ORIGINAL ARKANSAS HARDThe natural stone "Arkansas" has been used since antiquity for its fine granulation and its homogeneous distribution of the silicon particles. These characteristics guarantee an exact cross section without burr emergence on any kind of blades, where perfect sharpening is desired.
Application: with low viscosity oil, specific for natural stones.

ORIGINAL ARKANSAS SOFTIt possesses similar characteristics as the "Arkansas hard", is however assembled with larger masses the silicon particle, which are a few tenths of a Micron bigger. Being a softer stone, it can be applied to a wide range of applications. Its main characteristics are: fast removal of the metal, high friction ability, which permits a fast sharpening of blade and cut-off tools.
Application: with low viscosity oil, specific for natural stones. It can also be used dry for short utilization.
Cleaning: rub stone with sandpaper and water.
