i will literally go to the thrift store and pick up several all-metal pieces to replace it, just let me get rid of this one.
Do it. Maybe keep it in your room for a while if you live with your parents and they’re likely to notice and/or care, but if you live with roommates or a partner, you’re just doing maintenance by updating warped, damaged cutlery (unless they’re emotionally attached to this fork, but then just keep it as their personal fork).
It doesn’t have to be a secret, either, unless you live with unreasonable people.
