Natural vs. Synthetic Whetstones

Japanese Whetstones can be both natural and synthetic. Natural sharpening stones, sourced from quarries, possess unique traits admired by culinary enthusiasts. Natural stones, formed over millions of years, offer high precision with higher grits but lack it in lower grits. They are known for refining lower alloy blades and absorbing water for lubrication during sharpening. On the other hand, Synthetic stones prioritize consistency, affordability, and tailored sharpening for modern alloys. When Selecting a whetstone for knife Sharpening, the decision depends on individual preferences, values, and practical considerations.

Grit Variations

While Selecting whetstone for your knives, make sure to consider the grit size according to its particle size and finish smoothness. Grit sizes are categorized into rough (low), medium, and fine (high).

  1.  Rough stones (200-700) repair damaged knives.
  2.  Medium stones (800-2000) for general sharpening.
  3.  Fine stones (3000-8000+) focus on finishing and polishing.
  4.  Higher grits contribute to aesthetics, not necessarily sharper knives.

Selecting The Best Whetstones For Japanese Knives 

Japanese whetstones are praised for their exceptional qualities. In this discussion, we explore the three primary variants of traditional Japanese whetstones: Arato, Nakato, and Shiageto. Discover the distinct features of each variant, allowing you to choose a whetstone that best suits your needs:

Arato Stones (Rough Grit Stone):

Arato stones are considered one of the best knife-sharpening stones commonly used in Japanese culinary and woodworking traditions. These stones play a crucial role in honing the edges of blades, ensuring precision and sharpness.

Grit Levels and Types

With a coarse grit, Arato stones excel in initial sharpening, removing imperfections from blades. Often double-sided, these stones provide versatility, allowing users to progress from a coarse grit to a finer one for a polished edge.

Application in Culinary Arts

In Japanese culinary traditions, Arato stones are indispensable for maintaining knife sharpness. Chefs use these stones to ensure precise cuts, following traditional techniques that involve a multi-stone sharpening process.

Nakato Stones (Medium Grit Stone):

Nakato Whetstones have gained popularity for their exceptional quality and precision. These Japanese sharpening stones are renowned for being the best whetstone knife sharpener and their ability to bring out the best edge in blades makes them a popular choice for chefs and craftsmen.

Usage and Application

Nakato offers a diverse range of whetstones; it primarily produces water stones, a common choice in Japanese traditions catering to be used with water as a lubricant during the sharpening process. This not only aids in preventing heat buildup but also helps in carrying away debris, ensuring a smoother and more effective sharpening experience.

Grit Levels 

Understanding grit levels is crucial when using Nakato Whetstones. These typically offer a range of grits, each serving a specific purpose in the sharpening process. Coarser grits are suitable for repairing damaged edges, while finer grits refine and polish the blade.

Shiagato (Fine Grit Stone):

Shiagato stones are a type of natural stone highly valued in Japanese culture, particularly in the context of traditional craftsmanship like sword polishing and sharpening. These stones are known for their unique mineral composition and distinct characteristics that make them ideal for honing and refining blades.

Grain Structure

Characterized by a fine to ultra-fine grain structure, Shiagato stones play a crucial role in the precise honing and polishing of blades.

Modern Application

While rooted in tradition, Shiagato stones find modern applications in sharpening various tools, from kitchen knives to woodworking implements. Their exceptional sharpening qualities make them a preferred choice for those seeking precision and finesse in their cutting instruments.

Whetstone Sharpening Technique

Here’s how to sharpen a knife with a whetstone, step by step guide for beginners:
  1. Submerge the stone in water for 5 minutes to lubricate and aid in swarf removal.
  2. Use a non-slip base for quality stones, like the silicone base for a Priority Chef set (coarser side up).
  3. Determine the sharpening angle, marking the blade with a Sharpie for guidance.
  4. Let the knife's weight do the work; avoid applying undue pressure to prevent uneven sharpening and potential damage.
  5. Perform 12-15 trailing and leading strokes on each side, maintaining the correct angle.
  6. Begin with a lower grit whetstone and progress to higher grits to first address dullness and then refine the blade's sharpness.
  7. Hone with the fine grit side, feeling a slight burr, and then proceed to strop for an ultra-fine polish.
  8. Wipe the blade with a cloth to remove the swarf, completing the sharpening process.

Maintenance and Care

- Avoid soaking high grit stones; use water sparingly, and skip oil or other lubricants.
- Let the whetstone air dry thoroughly after use to prevent mold growth.
- Remove the non-slip base after sharpening for thorough drying.
