Arkansas Oil sharpening stone fine

RH Preyda was founded in Chicago in 2013 when the need for fine and quality natural stone grinders was discovered. Manufactured only in Arkansas, the stones are 100% natural and mined by hand. Arkansas grinders offer an excellent solution for industrial and consumer use.
Arkansas grinding stones come in a variety of colors, including white, gray, brown, black and more, but the latter does not distinguish between their grits.
Here is a general breakdown:
- Soft Arkansas is the coarsest of the three types of Arkansas stones. Its color is usually marbled, with colors ranging from white, gray, and black.
- Hard Arkansas is a stone with a fine grain. It is usually white in color, but light orange colors may be intermixed throughout the stone.
- Black Arkansas is a stone with a very fine grain. It is black or dark grey in colour.
