Bests & Worsts Reviews from Amazon

Heres why I wasn't impressed at first. I only used it for a few minutes on each side, which resulted in nothing. I watched a video online with a master chef using his stone, and he sharpened his knife for 10 minutes on each stone before moving up to a finer grit. I took this hint, and used sharpened my knife on each side of this stone for 10 minutes, which led to perfection. I have a Chef's knife from 2008 that I never used because it is so dull and impossible to sharpen using a traditional sharpening steel / rod. The steel seems to be very hard German steel, so there it sat in my knife block for years. This morning I spent 20 minutes with this stone, and it's back to being flawlessly sharp. Highly recommended.
