I don’t carry a knife, gets in my way. But I do use my $4.95 “Old Hickory” 8” kitchen butcher knife almost every day. Sharpened it once, about 5 years ago, until it shaved me. Carbon blade sharpens easily and holds up well. No problem with rust or discoloration, I always wash and towel dry immediately after use. I bring out my expensive knives only, when I feel a need to push out my chest, boast, and brag a little. Which, I do when someone comes around. LOL.
