A bread knife that cannot be sharpened with an ordinary whetstone. Then, if the sharpness gets worse, I have to buy a new one ...?
That's not true. Kai "Sharpener that sharpens wave blades" is a sharpener that sharpens bread knives with corrugated blades. The price is 1,620 yen.
Uses a grindstone unit that moves along the blade line. It is possible to sharpen without breaking the waveform of the bread knife. You can also sharpen ordinary knives.
Hold the handle of the sharpener with one hand and fix it. Insert the knife into the gap of the grindstone and sharpen it from the root to the tip. Finish after sharpening 10 times as a guide.
I sharpened it cleanly without breaking the wave blade! Rinse off the steel powder and you're done.
