Dimensions – 7,5 cm x 2,2 cm
Medium and Fine grit stone – 51/22 Micron | FEPA F 230/360 | ANSI 240/400 | JIS ~340/700
Microns are the universal size, as they’re a measurement of the actual grain diameter, but the other most common formats are ANSI (American), FEPA F (European), and JIS (Japanese).
USE : The medium grit is the dark greyside for the first passes, to restore the edge and takeout any small nicks. Finish off with a few more passes using the light grey fine grit side.
