The JewelStik 10 inch x 18mm Diamond Steel is the original oval-shaped sharpener that professional chefs have trusted for over 30 years. Crafted for precision and built to last, this two-sided diamond sharpener delivers consistent edges on a wide range of kitchen blades. The 10-inch length and 18mm width give you a stable, confident stroke, while the classic black handle provides a comfortable grip through long sharpening sessions.

Key advantages you won’t find in a plain steel

• Two-sided diamond surface—both sides are coated with durable diamond abrasive, promoting faster material removal and longer-lasting sharp edges compared to traditional steels.
• Oval design—the ergonomic shape keeps your knife at a stable angle, helping you consistently maintain an 18–22 degree edge for precise, controlled sharpening.
• Long, balanced profile—the 10-inch length provides smooth, uninterrupted strokes, reducing wrist fatigue and producing a uniform bevel along the blade.
• Made in the USA with a lifetime guarantee—fully manufactured, assembled, and packaged in the United States, backed by Hewlett's lifetime assurance.
• Versatile for many blades—ideal for chef’s knives, paring knives, and other long blades you rely on every day in the kitchen.

How to get the best edge

• Use long, steady strokes and aim to hold the blade at roughly 18–22 degrees for a balanced edge.
• Let the diamond surface do the work with light to moderate pressure; avoid pressing hard to prevent edge damage.
• Sharpen regularly to maintain performance, and flip to the opposite side to ensure even wear across the surface.
• After sharpening, wipe the blade clean and test the edge on paper or with a light cut to confirm sharpness.

Designed for practical, real-world use, this JewelStik sharpener stands out from basic steel rods by actively reconditioning blades with durable diamonds. It’s a dependable choice for home cooks and pro kitchens alike, providing quick results, consistent angles, and a dependable edge that lasts.
