The best knife sharpener for most people is a whetstone like the Sharpal 162N dual-grit stone, which sharpens any knife to a fine edge and lasts for years, with the Work Sharp electric sharpener as the easiest option for beginners. A sharp knife is safer and far more pleasant to use, so a sharpener is one of the best kitchen investments. The right one depends on whether you want control (whetstone), speed (electric) or simplicity (pull-through). This guide compares four knife sharpeners and how to choose.

Quick Answer

A whetstone like the Sharpal 162N gives the best edge and works on any knife, but takes practice. For ease, an electric sharpener like the Work Sharp is fastest, and a pull-through is simplest. Avoid cheap pull-throughs on fine Japanese edges.

How We Chose These Knife Sharpeners

We compared knife sharpeners by the quality of edge they produce, how well they suit different knives (including fine Japanese edges), ease of use, durability and value. We researched and spec-checked each option and reviewed owner feedback rather than claiming hands-on testing. Harsh pull-throughs that grind away too much metal were downgraded.

Key Takeaway: Honing and sharpening are different jobs. A honing rod realigns the edge between sharpenings and should be used often; a sharpener actually removes metal to create a new edge and is used occasionally. You need both.

Knife Sharpener Buying Guide

Whetstone vs Electric

A whetstone gives the best, most controlled edge but needs practice; an electric sharpener is fast and easy. See whetstone vs electric sharpener.

Honing vs Sharpening

Hone often to realign the edge; sharpen occasionally to create a new one. See honing vs sharpening and how to use a honing steel.

Japanese Knives

Fine Japanese edges are best sharpened on a whetstone, not a harsh pull-through. See how to sharpen a knife.

Safety Notes

  • Sharpen away from your body, with a stable stone or sharpener.
  • Keep fingers clear of the edge.
  • Wipe the blade after sharpening to remove metal dust.
  • A sharp knife is safer than a dull one.

What to Avoid

  • Harsh pull-throughs on fine Japanese edges.
  • Sharpening too often (removes metal unnecessarily).
  • Inconsistent angles that round the edge.
  • Skipping honing between sharpenings.
