Many people assume electric knife sharpeners are just quick fixes for dull blades, but this one surprised me with its precision and craftsmanship. When I first set the Chef’sChoice 15XV EdgeSelect on my kitchen counter, I expected a basic sharpen-and-go device.

Instead, I found a sleek, compact unit with a sturdy build and a surprisingly intuitive setup.

The three-stage system is where it stands out. The first two stages, plated with 100% diamond abrasives, quickly sharpened my dullest knives, transforming them into razor-sharp tools in under a minute.

The third stage, with its flexible abrasive system, polished my serrated blades beautifully, making even bread knives cut effortlessly again.

The adjustable spring guides feel like a smart feature, automatically tweaking to the perfect angle without much fuss. I appreciate how easy it is to operate—just flip the simple on/off switch, and you’re good to go.

I was surprised to find that this sharpener could make my dull kitchen knives feel like new in just a few strokes. It’s deceptively heavy—almost feels like a small brick, but that weight actually gives it a solid, confident grip on the countertop.

The first thing I noticed was the super flat surface, thanks to the MirrorFlat technology. Unlike my old water stone that wore unevenly, this stays perfectly level, ensuring consistent sharpening every time.

I tested it on a high-speed steel blade, and it cut through steel like butter with barely any effort.

The dual grit system is a game-changer. The coarse 325 grit quickly set the edge, while the extra fine 1200 grit polished it to a razor-sharp finish.

No mess, no fuss—just dry sharpening that’s clean and simple. I especially appreciated the included angle guide, which made it easy to keep my blades at the right angle.

The only downside? Its heavier weight might be a bit awkward for portability, but that stability is worth it for stationary use.

As soon as I unboxed the Diamond Sharpening Stone Kit, I was struck by its solid weight and sleek design. The three grit sides—400, 1000, and 8000—are clearly marked, and the tungsten steel slot feels sturdy and well-made.

It’s compact, yet it has a reassuring heft that makes sharpening feel stable and controlled.

The textured diamond surface feels rough but effective, perfect for fast material removal on dull knives. Switching between the grit levels is effortless—just flip the stone or slide it into the tungsten steel slot for more aggressive sharpening or fine honing.

The included angle guide is a lifesaver, helping me keep a consistent angle without guesswork.

Using the kit feels intuitive, thanks to the waterproof base which stays put on the counter or outdoor table. I especially like the leather strop; after sharpening, it smooths out the edge beautifully.
