Why Professional Chefs Choose These Whetstones

角度ガイド · THE ANGLE GUIDE
The clip that removes the risk
The single scariest part of sharpening a fine knife is ruining the edge. The included angle guide clips to the spine and physically holds your blade at a consistent 10–20° — the correct angle for Japanese and Western edges alike.
It's water-based too — no messy oils, no expensive solvents. Soak, sharpen, rinse with water. Clean-up takes seconds.

From the reviews
Real edges, from real kitchens
“Knives that are sharp again at last. After a short settling-in period, everything went brilliantly.”

“First time using one was so easy — and what an edge. Brilliant stones, just what I needed.”
Questions
Everything you need to know.
Do I need to use oil on these stones?
No - these are water stones, not oil stones. Simply soak them in clean water for 5 minutes before use and keep the surface wet while sharpening. No oils, no chemicals, no mess. Clean with water after each use.
What angle does the guide hold the knife at?
The angle guide helps you maintain a consistent 10–20° angle, which is ideal for most kitchen knives, including Japanese and Western styles. You can adjust within this range by changing how you hold the knife against the guide.
How to Use A Whetstone Angle Guide
Can I use these stones for other tools besides kitchen knives?
Yes! These whetstones work on any blade - chef knives, santoku, pocket knives, scissors, chisels, woodworking tools, and even axes. The versatile grit range handles everything from heavy repair to fine polishing.
How long do these stones last?
With proper care, decades. Unlike cheap whetstones that wear unevenly, our premium corundum stones maintain their surface integrity through hundreds of sharpening sessions.
Do I really need both stones?
Yes - they serve different purposes. The 400/1000 handles repair and general sharpening, while the 3000/8000 creates the polished, professional edge. Think of it as the difference between sanding wood with coarse then fine sandpaper.
How often should I sharpen my knives?
Home cooks: every 2-3 months with regular honing.
Professional use: monthly. If your knife won't slice a tomato skin cleanly, it's time to sharpen it.
Is this suitable for beginners?
Absolutely. The included angle guide and instruction manual make it straightforward. Most customers achieve excellent results on their first attempt.
