DH says he feels the need to follow me to the kitchen now having recently witnessed me using and washing knives, he also questions my food hygiene rules. I say I still have all my fingers and it's been a long time since I gave myself food poisoning so he's just being a worry wart.
I was washing dishes once when my in-laws were visiting, and DH was trying to help by clearing the table. Trouble was, he dropped a sharp knife down in the soapy dishwater. I told him to fish it out and never do that again, because having a sharp knife where you can't see it is a dingdangity good way to get a bad cut. MIL (as usual*) pitched a cat-haired fit. "And just how do you clean a knife if you don't put it in the sink?" I said "You hold it safely by the handle and dip it down into the water." She made a cat-butt face since she couldn't refute me on that, but she shut up about it.
*Any statement I made MIL was likely to challenge or take offense at, even so innocuous a statement as "What a nice day it is today."
I put the sharp knives soaking in left edge of the dishwater with handles toward me. No one touches my dishwater. Lucas used to have a fit about it, but I reminded him that I am the only one washing dishes and have never gotten cut. He's given up.
I would be angry if anyone else put anything in the sink, though.
Also, I keep my knives razor sharp, always use a cutting board, and it's years between accidents. My stepmother used to cut things on her thumb, and even when the knives weren't that sharp was constantly getting cut. Same behavior, same outcome. Duh. I didn't eat her salads until I checked the condition of her thumbs - yuck.
I recently bought a ceramic knife made by Quisinart. I returned it because it wasn't sharp enough.
