DUAL SIDED SHARPENING- Made from durable silicon carbide, this two-sided sharpening block comes with both a 400-grit side, used for returning edges to their original shape, and a 1000-grit side used for smoothing and polishing cutting edges. WATER STONE- This stone is meant to be used with water, not oil. Simply soak stone for 5-10 minutes before use, and lubricate with additional water as needed when sharpening. No expensive honing oil needed! MULTI USE TOOL- This whetstone can be used as a one-stop shop for any item you want sharpened and polished, including kitchen cutlery, scissors, hunting or pocket knives, blades, and razors. Also works for hatchets, axes, carving and gardening tools.
