We have manufactured Diamond Knife Sharpeners for over four decades. Our diamond knife sharpeners are used both personally and commercially - from hunters and fisherman to chefs and butchers worldwide.
Hewlett Manufacturing was a pioneer in the development of diamond coating technology. Our first diamond wheel established an all-time record for efficiency.
Since their introduction in 1983, JewelStik has become the world standard with chefs, butchers, fishermen and others who use knives professionally.
Hewlett Manufacturing is the original inventor of the lens shaped diamond sharpener. Everyone has copied us, and copied us poorly. Some on the market offer an interupted surface - one with holes throughout - this accomplishes two things: it gives you less surface and less diamonds.
Trust the quality and durability that only comes from the United States. You can depend on JewelStik.
