This is a japenese hybred and has 15 degree angle on both sides. I don't know if there is a good electric sharpener out that can maintain it's sharppness. It is fairly pricey so if I can't maintain it's orginal condition it might not be worth.
I do sharpen knives by hand but only western 20 degree knives. A 15 degree VG-10 might be tricky. Maybe I am making more out of this than is necessry but it would really be bummer if it became no sharper than my western knives.
