Masahiro

The Masahiro 195mm Deba Sheath (or saya) is made of Ho-Wood (Japanese Magolia Tree) and is used to protect your Traditional Japanese blade. These types of knives can vary slightly in shape and thickness, so if you have a brand other than Masahiro, the saya may not fit. These are raw wood and you may wish to treat the saya with mineral or chamomile oil which makes them more resistant to staining should they come in contact with food Learn More

A fast-cutting 600 grit waterstone that removes material quickly while leaving an edge refined enough to move directly to 3000 grit. The Masahiro 600 Grit is the stone to reach for when a knife has fallen past maintenance and needs to be brought back efficiently. It cuts quickly and predictably, making it easy to re-establish an edge without overworking the blade. What sets this stone apart is the finish it leaves. Unlike most stones in this range, it produces a cleaner scratch pattern, which allows you to move straight to a 3000 grit for refinement. You can skip the 1000 grit step entirely if you prefer a more efficient progression. This makes it especially useful for routine edge recovery on working knives, perfect for when the edge is worn down but not heavily damaged. It will raise a consistent burr quickly, with clear feedback throughout the stroke. You can feel exactly when the edge is ready to move on, which helps maintain control over pressure and angle. This is not a heavy repair stone. For large chips or full reprofiling, a coarser grit is still required. Soak the stone before use and keep the surface wet during sharpening. Like all waterstones, it will wear over time and should be flattened periodically to maintain a consistent surface. Learn More

This 3000-grit traditional waterstone delivers a comparatively high polish for its grit, paired with excellent cutting abrasion. This is an ideal final stone for an all-purpose blade. This 3000 grit also fits naturally into more advanced sharpening progressions: stones in the 2000-4000 grit range sit in the middle of the spectrum, following a coarser 400-1000 grit stone that shapes the edge and removes any chips, then refining that edge past the coarser scratch pattern it leaves behind. In a three- or four-stone progression, this stone serves as that middle stage, preparing the edge for a higher-grit (6000+) stone to follow for a mirror polish. In a simpler two-stone setup, though, it works just as well as the finishing stone itself, producing a keen edge with excellent cutting bite. As a traditional waterstone, it requires a short soak in water before use — it is not a splash-and-go tool. Testing shows it holds up harder and more durable than the King 3000, with better flatness retention over repeated use. Chef Feedback “We love the finish derived from this 3000 grit fine stone. It doesn’t ‘load up,’ cuts quickly, develops slurry fairly easily, and puts a finished edge on a knife that’s comparable with other brands of much higher grit. Highly recommended.” Learn More

The Hard, Durable Core of Professional Sharpening In the world of professional cutlery, finding a balance between hardness and durability is often an exercise in compromise. Masahiro defies this convention. This 1000 grit medium waterstone is specifically designed to service steels that represent an exceptional anomaly—blades that are incredibly hard and wear-resistant, yet maintain a durability that prevents brittleness. The MH40103 is the essential bridge between coarse repair and fine polishing, providing the tactile feedback required to set a perfect primary bevel. Unlike standard synthetic stones that can feel 'mushy' or wear down unevenly, this Masahiro traditional waterstone maintains its flatness longer while providing a consistent slurry. It is the workhorse stone for the high-volume kitchen. Whether you are maintaining a line of Masahiro's own proprietary steel or any high-end Japanese carbon blade, this stone handles the density of the metal without glazing over. The generous 2-7/8 inch width provides a massive landing zone for larger chef's knives and cleavers, ensuring stable, full-blade strokes that result in a uniform edge from heel to tip. Where most stones require external holders that can slip on wet stainless tables, the Masahiro Medium 1000 comes equipped with a heavy-duty, integrated stand. This isn't just a convenience; it is a safety and precision feature. By raising the stone off the work surface and providing a non-slip base, it allows for a more ergonomic sharpening angle and prevents the 'knuckle-knock' common with low-profile stones. This is the definitive tool for the chef who demands an edge that holds up through 40 pounds of prep without the fear of chipping. Learn More

This authentic Masahiro Saya is carved from Japanese Ho-wood (Magnolia), a material prized by bladesmiths for its low resin content and ability to resist moisture without imparting oils or odors to the steel. During hands-on testing with the MH16207 model, the tactile feedback of the friction fit is immediate. There is no rattle or lateral movement. The wood grain provides enough natural grip to hold the blade securely, yet releases smoothly when pressure is applied. Unlike plastic guards that can trap humidity against a carbon steel face—leading to rapid oxidation and pitting—the breathable nature of Ho-wood helps regulate the micro-environment around the blade. This is essential for maintaining the refined edge of a Deba used for heavy fish butchery. Handling the saya, you will notice the light, almost airy weight of the Magnolia wood, which adds negligible bulk to your knife roll while providing a rigid physical barrier against impact.

The Masahiro 8.25 in. (210mm) Usuba Sheath is a Ho-wood sheath (or saya) that is very specifically sized by each manufacturer. These fit very tightly and be wary of companies selling generic models for Japanese knives. If it isn't made for your knife, it simply won't fit properly. We suggest using mineral or chamomile oil to saturate the handle of the knife and the saya. This provides protection from staining.

In a professional sushi kitchen, the 330mm Yanagiba is a significant investment that requires more than just careful handling; it requires dedicated protection. This authentic Masahiro Yanagi Sheath (Saya) is crafted from Ho wood (Japanese Magnolia), the gold standard for knife storage. This wood is specifically chosen by Japanese bladesmiths for its low acidity and moisture-wicking properties, which are essential for preventing oxidation on high-carbon steel blades. When sliding a 330mm blade into this saya, you will notice the friction-fit precision. Unlike generic plastic guards that can trap debris or scratch the finish, the soft-grained Ho wood cushions the blade, ensuring the delicate 'Urasuki' (the concave back side of the Yanagi) remains pristine. While designed as the perfect companion for the Masahiro MH16222, this sheath provides the necessary internal clearance for various traditional 330mm Yanagiba profiles. It is a tactile, lightweight solution for the chef who travels between stations or requires secure off-bench storage. The unfinished wood surface allows the material to breathe, naturally regulating the micro-environment around your steel to prevent the 'sweating' often seen in synthetic covers. Learn More

The Masahiro 12 in. (300mm) Yanagi Sheath is a Ho-wood sheath (or saya) that is very specifically sized by each manufacturer. These fit very tightly and be wary of companies selling generic models for Japanese knives. If it isn't made for your knife, it simply won't fit properly.
