^One of these?
I never found one that I didn't thought took off WAY more than just the peel!
But you should still buy the honing rod and sharpening stone from the manufacturer of your main knife.
One thing I hate is the language they sometimes use. For one, almost everyone calls honing rods "sharpening rods" which is just a total misnomer. And when you run a blade across a stone, you're really not "sharpening" it so much as giving it a finer hone.
A proper sharpening involves special tools that basically get rid of the old edge to create a new one.
My bad engrish; what you say here sounds like something I would have said had I had the words. (although, I wouldn't have been that thorough). -Thanks for pointing out these things
