Types of Whetstones


Definition

Nakato (中砥) refers to a medium-grit whetstone, typically ranging from approximately #1000 to #3000 grit. It is the most commonly used sharpening stone in knife maintenance and serves as the foundation of routine sharpening for both professional chefs and home cooks.

Details

Nakato occupies the middle stage of the traditional Japanese sharpening process, positioned between coarse stones (Arato) and finishing stones (Shiageto).

Its primary functions include:

  • Restoring dull edges
  • Refining scratches left by coarse stones
  • Maintaining everyday sharpness
  • Preparing the edge for finishing stones
  • Preserving blade geometry

Because it balances sharpening speed with control, Nakato removes enough steel to restore performance without excessively wearing down the blade.

Common grit ranges include:

  • #1000: Ideal for restoring dull knives
  • #2000: Suitable for regular maintenance
  • #3000: Provides a finer edge while remaining practical for daily use

For many kitchen knives, especially those used regularly, a Nakato may be the only whetstone needed to maintain effective cutting performance.

Comparison

Nakato serves a distinct role compared to other whetstone categories.

Arato (Coarse Stone)

  • Typically below #1000 grit
  • Aggressive material removal
  • Used for repairing chips and reshaping edges
  • Leaves deep scratches

Nakato (Medium Whetstone)

  • Typically #1000–#3000 grit
  • Balanced sharpening and refinement
  • Ideal for regular maintenance
  • Most frequently used sharpening stone

Shiageto (Finishing Stone)

  • Typically #4000 grit and above
  • Creates highly refined edges
  • Improves cutting smoothness
  • Used after Nakato for maximum sharpness

Compared to coarse stones, Nakato provides greater control and produces a cleaner edge. Compared to finishing stones, it offers faster sharpening and more practical maintenance for everyday use.

Practical Use

Nakato is considered the workhorse of knife sharpening.

Typical applications include:

  • Restoring moderately dull kitchen knives
  • Maintaining Japanese knives between major sharpenings
  • Refining edges after coarse grinding
  • Preparing blades for finishing stones
  • Routine professional knife maintenance

Both synthetic and natural versions are available.

Synthetic Nakato

  • Consistent grit size
  • Predictable performance
  • Easy to use
  • Widely available

Natural Nakato

  • Unique sharpening characteristics
  • Rich tactile feedback
  • More variable performance
  • Valued by enthusiasts and traditional sharpeners

For most users:

  • A #1000 stone is sufficient for restoring sharpness.
  • A #3000 stone is excellent for maintaining already sharp knives.

Many professional sharpeners consider a #1000–#3000 combination to be the most practical setup for routine knife care.

Cultural Note

In Japanese sharpening culture, Nakato is often regarded as the "workhorse stone" (shigoto no toishi). While coarse stones repair damage and finishing stones attract attention for producing mirror-like edges, Nakato performs the majority of sharpening work.

Its importance lies in consistency and reliability rather than prestige.

Japanese chefs traditionally view sharpening not as an occasional repair but as an ongoing discipline. The Nakato supports this philosophy by making regular maintenance both practical and effective.

For generations, professional chefs have relied on medium-grit stones to maintain the sharpness necessary for Japanese cuisine, where precise cuts directly influence texture, appearance, and flavor.

In this sense, Nakato embodies an important aspect of Japanese craftsmanship: the belief that excellence is achieved through steady, consistent care rather than occasional dramatic intervention.
