Chefs have relied on this original JewelStik for over 30 years, and its enduring design continues to set the standard for performance and longevity.
Why this sharpener stands out
- Dual-sided diamond surface: Diamond is on both sides, giving you consistent sharpening in one tool and extending its usable life before flipping or swapping accessories.
- Oval shape with a traditional black handle: The ergonomic form helps you maintain a steady angle, promoting control and comfort during extended sharpening sessions.
- Proven angle guidance: Aim for an edge bevel of roughly 18 to 22 degrees for a durable, keen edge on a wide range of blades.
- Made in the USA: Completely manufactured, assembled, and packaged stateside, with Hewlett standing behind the product with a lifetime guarantee.
- Versatile length: The 10-inch length is ideal for long blades like chef’s knives, slicers, and many kitchen workhorses, while still being nimble enough for smaller tasks.
Ideal use cases
- Professional kitchens sharpening chef’s knives, santokus, and slicers to maintain precise cutting performance during service.
- Home cooks who want a reliable, long-lasting sharpener that preserves blade bevels and reduces the need for frequent replacements.
- Culinary students seeking a proven, user-friendly tool that teaches consistent edge geometry and angle control.
How to get the most out of your JewelStik
- Set your blade to a comfortable 18–22 degree angle and maintain that tilt as you draw the edge across the diamond surface.
- Sharpen with light, steady strokes on each side to build an even bevel—avoid excessive pressure that could over-stress the edge.
- Wipe the blade clean after sharpening and dry the steel to prevent any moisture-related corrosion.
- Regularly inspect the diamond surface; with two sides in play, you’ll know when it’s time to rotate or re-dress for uniform results.
