A sharp knife makes a safe kitchen, but there are so many conflicting schools of thought out there that learning how to sharpen your own knives can be overwhelming. My philosophy is this: I'm a cook, not a bladesmith. I need a fast, reliable sharpening method because I don't have backup knives to use while mine are at the hardware store getting sharpened and I don't care to spend a couple decades mastering the art of honing a blade.
