JewelStik 12″ x ¾” Diamond Steel

The JewelStik 12″ x ¾” Diamond Steel is a professional-grade diamond sharpening steel trusted by chefs, butchers, anglers, and outdoor enthusiasts for more than 30 years. Manufactured in the USA by Hewlett Manufacturing, this premium sharpening tool is designed to quickly restore razor-sharp edges on longer knives, making it ideal for fillet knives, chef’s knives, butcher’s knives, and other large cutting tools.

Unlike traditional honing steels that simply realign the cutting edge, the JewelStik features a dual-sided diamond-coated sharpening surface that actively removes a small amount of steel, allowing dull blades to be restored quickly and efficiently. The industrial diamond abrasives provide fast, consistent sharpening, helping maintain peak cutting performance with fewer strokes.

A key feature of the JewelStik is its oval (lens-shaped) shaft, which offers greater surface contact than conventional round sharpening steels. This innovative profile makes it easier to maintain a consistent sharpening angle—typically between 18° and 22°—producing a sharper, more even edge while improving control throughout the sharpening process.

Measuring 12 inches long by ¾ inch wide, this larger model is particularly well suited for sharpening longer blades. As a general guide, your sharpening steel should be at least as long as the knife blade being sharpened, making the JewelStik 12″ Diamond Steel the ideal companion for larger fillet knives and professional kitchen knives.

The traditional black ergonomic handle provides a comfortable and secure grip, while the lightweight yet durable construction makes it easy to use whether you’re maintaining knives at home, in the kitchen, on the boat, or at the fish cleaning station.

Proudly manufactured in the USA, the JewelStik is built to professional standards and backed by a lifetime guarantee, providing confidence that it will continue delivering exceptional sharpening performance for years to come.
