The emulsion includes a water-soluble salt of an ether compound or a chloride compound or both in an amount sufficient to preserve the cutting edge of a utensil, a hydrophobic substance in an amount sufficient to reduce water contact with the edge of the utensil, and an alcohol in an amount sufficient to assist in solubilizing the hydrophobic substance. Immersion of the utensil in the emulsion preserves the sharpness of the cutting edge to facilitate longer service of the utensil.
