Let's see if I can enlighten. When I got Shrek, he was housebroken, but not trained. I could trust he would not act out too much
in public and he treated others with respect. However, once he got home the gloves were off. He put knives in the sink, he used them in the pots and pans, he once used a bread knife to cut the handle down on a broom (I still don't know why) and his knives were just tossed in a drawer with everything else. The knives were a horrid mess.
I introduced him to my, inexpensive, but quality knives, mostly knives my Dad gave me when he would replace his own knives. I was willing to allow the ogre of my life to use my knives...to my horror, he tossed out the cardboard sleeves they had and treated them like his knives. Even as he mistreated them, he extolled on the sharpness and handling of my once beautiful knives. The day I cut my hand open on a knife tossed in the dish water was the last straw. I gifted him my set of knives and prevailed upon my Dad to help me purchase another set.
Shrek and I have an understanding, no knives in dishwater (there was a lot of blood) and my knives are off limits, even now after 31 years...he is "The Knife Killer" and accepts his role in life.
But, not everyone is as possessive as I am of my knives and some are more so. I understand the OP not wanting his wife to feel like he usurping her role as nurturer of their family. However, while it is needed in their case, he deserves to have the tools that he feels comfortable with. If she gives her approval then he can do as he needs in "her" kitchen, including replacing the knives she has used, for something he would like to use.
