This is a little off topic but the expertise is here.
My wife brings these to me about twice a year for sharpening. Mostly they need cleaning (dripping with oil and packed with hair). I give them a quick rub on the 3000 stone to remove any varnish or burrs that might be there. They seem sharp but I have no way to test them, unless one of the cats strays near and I'm not sure that would be the right type of fur to test them on. Don't want to go deep on something that is already sharp.
