As someone who washes his knives in the dishwasher (please, don’t hurt me), I think you’ve just inspired me to take better care of my knives. Think I might stop putting them in the dishwasher and hand wash them instead and get at least some kind of basic knife sharpening system. I’ve got a couple of knives that could use the little bit of extra care so I’m not struggling every time I need to use them.
