I had this knife for at least 20 year. I use a Wusthof sharpener and the knife is still insanely sharp. I probably should take better care of it and there handle has a few scratches on it.

But still and awesome knife and with the sharpener very sharp after 20 years of use.

I wouldn't trade it for a new one and plan on passing it on to my son when I can no longer use it...
