Level 4 - Medium
The level 4 or medium grit is an in-between grit. It is well suited mainly as a grit to use after a coarser grit and before a finer grit. It sharpens more slowly than coarser grits but does not leave as refined of an edge as the finer grits.
Grit: 300 - 400 Grit
Particle Size: 35 - 45 Micron
