A dull knife in the kitchen can ruin any meal. Keep your knives sharp with this easy-to-use whetstone kit. Whetstone features two sides: coarse for forming a new edge and repairing nicked blades and fine for sharpening blades to a razor edge. Included guides hold blades at the proper angle for perfect results every time, while the storage box elevates and protects the stone while sharpening and provides a tidy space to store everything when not in use.
