A must have upgrade!
If you already have a Ken Onion knife sharpener then you already know how useful it is. Now you can step it up a notch with the blade grinding attachment, I've had mine for a few years now and i can truly say this is a must have! My knives are OMG sharp! This handles sharpening most anything you can think of, I've even used it to sharpen a katana, Easy to use and the results are amazing. You have a "super steel" that just won't get sharp? Not a problem with this baby. Just buy it! You won't regret it.
