Goodjob GB-3D Diamond Sharpening Stone – 3-Side Grit 400/1000/8000 with Angle Guide & Non-Slip Base

Meet the Goodjob GB-3D Diamond Sharpening Stone

Designed for home cooks, knife enthusiasts, and professionals, the GB-3D blends industrial diamond with ceramic for a versatile sharpening system that adapts to blades across a range of steels. The durable construction, paired with a stable base and clear angle guidance, helps you move from dull to refined with confidence, while delivering practical results without hype.

Three grit system in one

• 400 grit diamond stone for edge repair and restoring blunt blades
• 1000 grit diamond stone for regular maintenance and honing to a fine edge
• 8000 grit ceramic stone for ultra-fine finishing and polishing

The tri-grit progression reduces the need to switch stones, offering a straightforward path from rough repair to a polished edge. The combination is paired with a wide, non-slip base that stays steady on your counter, and an angle guide to help you sharpen at set angles.

How to use

• Wet the stone with water or honing oil to reduce friction and carry away particles.
• Choose the angle: 14° for narrow blades, 17° for most kitchen knives, or 20° for tougher steels.
• Sharpen with controlled strokes, then rinse and dry after use.

Durability is a highlight: the industrial diamond layer enables fast sharpening across blade hardness levels, while the ceramic layer finishes and polishes for a smooth edge. The kit includes a 3-year after-sales service, making it a thoughtful gift for chefs or knife collectors.

Who is it for

Ideal for home kitchens, professional environments, or hobbyists who value a repeatable, safe sharpening routine. The design supports everyday use with straightforward maintenance and predictable results.

Care and maintenance

• Rinse after use to remove metal particles.
• Keep the surface clean and dry to preserve grip.
• Avoid extreme heat to protect the base and guide accuracy.
