Beginner-friendly model with “angle-fixing guide & whetstone stand/storage case combo” – achieve professional sharpness even on your first try! This compact all-in-one set lets you complete everything with just one item. “My knives aren’t very sharp anymore.” “I want to try sharpening them, but it seems difficult.” – This whetstone set was created to solve these problems. A whetstone is a tool used to sharpen metal blades by abrasion, restoring their sharpness. This product comes with an “angle-fixing guide” that simply attaches to the back of the knife to maintain the optimal sharpening angle. Even those with no experience can sharpen at a consistent angle. Furthermore, it comes with a dedicated plastic case for storage after use, so you won’t have trouble finding a place to keep it. This is the perfect set for anyone looking to achieve “easy, simple, and sharp” results on their first attempt.
Hard, strong, and resistant to wear – “Corundum Whetstone” recognized by professionals. This product uses “corundum (alumina),” a mineral second in hardness only to diamond.
・Exceptional sharpening power (abrasive force)
Due to its composition of extremely hard particles, it can quickly sharpen blades of all metal types, from stainless steel knives to high-speed steel chisels. This also reduces work time.
・High durability and surface retention
It is resistant to abrasion and less prone to “wear,” where the whetstone itself becomes recessed during sharpening. It maintains a flat surface easily, making it suitable for precision planing and sharpening of tools like planes and chisels.
・Consistent results
The uniform particle size minimizes unnecessary scratches on the blade, resulting in a sharp, even edge.
■ #1000 (Medium Grit – for Basic Use)
Features: This is the most standard grit, offering a balance between sharpening power and finish. If you have a household with general needs, this single stone is sufficient to restore adequate sharpness. Because it is made of corundum, blades are sharpened more quickly than with conventional whetstones.
【Purpose/Use (#1000)】“If you’re unsure, start with this one. Ideal for everyday household knives and professional tools, restoring sharpness for daily use.”
・Routine Maintenance: Use for regular sharpening when you feel your knife has lost its edge.
・Removing Scratches After Coarse Grinding: Smooths out deep scratches left by #400 grit and refines the blade.
・Sharpening (Full Sharpening): Restores a dull edge, creating a “blade” that bites into food.
Main Compatible Blades (limited to metal excluding titanium): Tools with thicker blades used roughly, and blades requiring high abrasive force due to their hardness.
Outdoor/Agricultural Tools (prone to chipping): Axes, billhooks, sickles, hedge shears, lawn shears
Thick Cooking Knives (for significant correction): Deba knives, small Deba knives, Aji-kiri knives, Salmon-kiri knives, Gyuto knives, Kiritsuke knives, stainless steel Chinese cleavers
Special/High-Hardness Tools (requiring abrasive force): Ice carving chisels (due to harsh usage conditions)
High-speed steel chisels/planes (initial sharpening when medium-grit stones take too long due to high hardness)
・A complete set with all the tools needed to achieve professional results and sharpness.

The set includes not only sharpening tools but also maintenance considerations, such as a sharpening stone for smoothing the main whetstone when it wears down. The tall whetstone stand makes sharpening easier and ensures a stable finish. Of course, it also includes an angle-fixing holder for beginners to maintain a consistent blade angle for a sharp edge. A dropper for convenient water supply to the whetstone and a rubber base to protect the whetstone are also included.
All tools can be stored in the dedicated case.
・The convenient double-sided whetstone can handle a wide range of tasks, from repairing chips to finishing!
■ #400 (Coarse Grinding/Correction)
Features: Characterized by its large particle size and rough surface. This grit offers the most noticeable sharpening power of corundum, allowing you to quickly remove material even from hard metals.
■ #1000 (Maintenance/Finishing)
Features: This is the most standard grit, offering a balance between sharpening power and finish. If you have a household with general needs, this single stone is sufficient to restore adequate sharpness. Because it is made of corundum, blades are sharpened more quickly than with conventional whetstones.
※If necessary, use a separate #3000 grit to achieve an even sharper, mirror-like finish. However, the #1000 grit provides sufficient sharpness and a good balance of strength and edge retention for normal use.
