Can I use an electric sharpener on my Japanese knife?

Not recommended. Most electric sharpeners are too aggressive for Japanese knives and can:

• Damage the thin edge

• Change the original blade angle (typically 15° on Japanese knives)

• Shorten the knife’s lifespan by grinding away too much steel

To preserve sharpness and performance, we recommend using a whetstone or having your knife professionally sharpened. If you prefer a sharpening device, choose one specifically designed for Japanese knives with a 15° angle.
