I agree with Larry in KY. I have tried all the sharpeners discussed so far plus a few more and I have never been happy with them.
Enter the Edge Pro. I got the Pro model and it is fantastic. It allows me to be very precise, since I shake a little. My friends have been very happy with the highly polished, precise bevels with a durable, sharp edge.
Ben Dale also give great service and will help you with whatever you need.
Some might hesitate to spend the required money, but if you have thousands tied up in blades, it only makes sense to spend a little to treat them well.
