- Definition: The small step or gap found between the blade and the handle of a Japanese knife, serving structural, functional, and aesthetic purposes.
-
Details: Machi is positioned between the ago (heel corner of the blade) and the nakago (tang inside the handle). Its presence and size differ depending on the knife type—yanagiba and usuba often feature a visible machi, while deba and nakiri generally show little or none.
-
Comparison: In Western knives, blade length is typically measured from bolster to tip, while in Japanese knives it is measured from the machi to the kissaki (tip). This distinction means a “210 mm” yanagiba with a machi may have a shorter exposed edge compared to a Western counterpart of the same nominal size.
-
Practical Use: Machi contributes to durability and balance by reinforcing the connection between blade and handle. It also absorbs some stress during use, preventing cracking or loosening. Additionally, the presence of machi allows more precise re-handling or replacement of handles.
- Cultural Note: Beyond function, machi is an aesthetic element in fine Japanese knives, often finished with care by the craftsman. Its subtle presence is appreciated by connoisseurs as a mark of authenticity and traditional construction.

镁质结合法
- Definition: The magnesia bonding method is a manufacturing technique for artificial whetstones that uses magnesia cement as a binder, producing stones with distinctive properties.
- Details: In this method, abrasive grains are mixed with magnesia cement (magnesium oxychloride), kneaded, and then hardened at room temperature without firing. The resulting stones absorb little water, allowing them to be used immediately without soaking. They provide strong grinding power, smooth sharpening performance, and are available in a wide range of grit levels. However, long-term soaking can damage the stone, and aging may lead to brittleness or cracks.
- Comparison: Unlike vitreous-bonded whetstones, which are fired at high temperatures, magnesia-bonded stones are dried at room temperature, giving them superior immediate usability but lower long-term durability. Compared to resinoid-bonded whetstones, they offer stronger sharpening power but are more vulnerable to prolonged water exposure.
- Practical Use: Magnesia-bonded whetstones are particularly popular as finishing stones due to their smooth sharpening feel. They are well suited for fine edge refinement but require careful handling, including thorough drying and proper storage, to ensure longevity.
- Cultural Note: In Japan’s knife-making and sharpening culture, magnesia-bonded stones are valued for their efficiency and refined sharpening touch. Professional chefs and sharpeners often select them when precision and speed are required, despite their relatively shorter lifespan compared to other bonded stones.
