Narcissus Knife Sharpener S867 - Fast Diamond Sharpening for Home

In this review of the Narcissus Knife Sharpener S867 the bottom line is clear: this electric, diamond-abrasive unit is aimed at home cooks who want professional-style edge maintenance without the fuss of manual stones. It excels at restoring cutting performance quickly thanks to a dual-stage system that combines a crude slot for rapid material removal and a fine slot for polishing to a burr-free edge. For anyone with mixed blade types and a busy kitchen, the S867 makes regular sharpening fast, repeatable, and safer than handheld methods.

Key Features

• Dual sharpening system: The crude slot removes dull metal quickly while the fine slot polishes the edge to a smooth, burr-free finish for consistent results.
• Diamond abrasive wheels: Diamond wheels cut faster and last longer than conventional abrasives, so straight, serrated, and ceramic knives get a sharp edge with fewer passes.
• 3-in-1 versatility: The unit also works as a scissors sharpener, which reduces the need for a separate tool and saves kitchen storage space.
• Stable motor and cooling: A 30-watt DC motor provides continuous operation for over an hour without overheating, letting users sharpen several blades in one session.
• Reduced vibration design: A lower center of gravity plus four anti-slip feet and an ergonomic handle minimize movement during sharpening for safer, steadier use.
• Wide voltage compatibility: The 100-240V design allows the sharpener to be used reliably with different household power systems.

Who It's For

The Narcissus S867 is well suited for home cooks, small household kitchens, and anyone who prefers an electric solution to keep chef and utility knives in ready condition. It is particularly useful for users who want to sharpen a variety of blade types - including straight, serrated, and ceramic - and who value speed and repeatability over learning a whetstone technique.

Those who should look elsewhere include professional sharpening services or users seeking full control over bevel angle for custom edge profiles; dedicated sharpening with stones or guided systems offers finer control for advanced knife tuning. Also, if portability without mains power is essential, a manual sharpener or pocket stone may be more appropriate.

Pros & Cons

Pros

• Restores sharpness quickly with a clear two-step process that is simple to follow.
• Diamond wheels provide durable, efficient cutting for faster sharpening than many other materials.

• Built-in scissors capability adds useful versatility for a single countertop tool.

Cons

• Some users note variability in wheel floatability, which can affect very fine tuning on some blades.
• Electric operation means it is less convenient for off-grid use compared with manual systems.
