This is a vintage 1950s Cory Model DKS electric knife sharpener in unusually nice original condition, and best of all it works perfectly. It is rare to find one of these vintage knife sharpeners in such nice condition. Its case, bottom rubber base, sharpening wheel and even the cord are excellent. T is only minor wear w the knife rests on the metal guides on either side of the sharpening wheel. These vintage Cory sharpeners are very heavy duty and work beautifully to keep all of your knives razor sharp. This item has been fully tested and works perfectly.
