How can I dispose of old kitchen knives? I bought a set of knives a couple of years ago and they have since dulled and rusted. I'm not sure if it's a good idea to just throw them in the garbage. I would normally try to make do with them, but I received a better set of knives as a gift recently and kind of wanted to clear out my kitchen drawer. - Malaika thrift store charity. We assume they're steel, and not stainless steel (from the rusting) - so why not scrub them down and have them sharpened? If they are sharpened and clean, they would make a good donation item, and it would keep them out of the landfill a little longer! If they are in really bad shape, though - totally unusable - we would wrap them securely in several layers of newspaper and trash bags (to keep any sharp edges from poking through) and pitch them. Any other thoughts on recycling or donating?
