Sharpening Oilstones , Iran

Sharpening oilstones consist of abrasive particles like alumina or silicon carbide. Particle sizes range from 250 to 800 grit with a tolerance of ±15 grit. They feature 20% to 30% porosity for lubricant retention. Their bulk density is between 2.2 and 2.5 g/cm³. Their hardness is rated 7 to 9 on the Mohs scale. Standard block dimensions are typically 200 x 75 x 25 mm. Their edges are finished to a 0.5 mm precision.

These stones structure combines abrasive grains with ceramic or resin bonds. They use mineral or synthetic oil as lubricant and coolant. The oil flushes swarf particles from the pores. This process prevents surface glazing. The optimal sharpening angle is maintained between 15 and 25 degrees. Manual working speed is typically 0.5 to 1 meter per second. A quality stone can sharpen over 500 household knives.You can order and buy Sharpening Oilstones from Iran by contacting us through whatsaap and email.
