Presto 08800 EverSharp Electric Knife Sharpener

1. Presto 08800 EverSharp Electric Knife Sharpener

  • Brand: Presto
  • Manufacturer: Presto

The Presto 08800 EverSharp is a compact and affordable 2-stage electric knife sharpener designed to restore a razor-sharp edge to non-serrated kitchen and sport knives. Utilizing Sapphirite sharpening wheels, the same ultra-hard material found in professional sharpening tools, this device offers a simple, no-guess sharpening process. Its precision blade guides ensure that knives are held at the optimal angle during sharpening, making it user-friendly for beginners. The lightweight plastic construction and compact footprint make it ideal for small kitchens or occasional use.

In performance tests, the Presto 08800 excelled at sharpening standard kitchen knives, producing a clean, sharp edge within seconds. However, it struggled with thicker blades and lacked the versatility to handle serrated or ceramic knives. The two-stage system—coarse grinding followed by fine honing—delivered consistent results, though the lack of a polishing stage left some edges less refined. For its price point, it offers excellent value, but its limited functionality may not suit more advanced users or those with diverse knife collections.

Pros

  • Affordable price point
  • Compact and lightweight design
  • Easy-to-use precision blade guides
  • Effective for standard kitchen knives

Cons

  • Limited to non-serrated knives
  • Plastic construction feels less durable
