>> I will take those knives to a pro and he will sharpen them for me, as in a rental I stay in, I don't have the tools to do that and as I said in another comment - I don't have a pain free process to do that as I don't do it often

Do you also replace your elderly relatives' Windows XP with linux distros, because linux is a better OS?

The moment you return the sharpened knives to your partner and she starts using them, she'll cut herself, with a small probability for a serious cut that will leave permanent damage to her hand.

Think carefully.
