Cheese Knife - The Original Cheese Knife

The Cheese Knife is made of a revolutionary new material that keeps the cheese on the plate, not on the knife.
Originally designed as a soft-cheese knife, the technology also works with butter, fois gras, boiled eggs, cake, or any substance that typically leaves a residue on ordinary blades.
The smaller knife itself measures a total of 8 inches long with a 3.75 inch blade edge.

Note: Product dimensions are approximate, knife ships in cardboard sheath.
