Or it's worth buying a decent power sharpener. One black friday I picked up a worksharp(1/2 in belt sharpener with jig) and it's right up there with the microwave and instantpot for being worth the money and space in the kitchen. A few times a year I sharpen every single non-serated knife in the kitchen (2 blocks) and it only takes like 5-10 minutes total. And yea having a few extra cheap chefs knives lets me push it to 6 months or so till I start running out of sharp chefs knives.

Or the bottom of a coffee mug. Takes a bit of eyeballing to get it right the fist time, but sharpens up, good!

Yeah, I did that at an AirBnB (I think I learned of it from Kenji Lopez-Alt / Serious Eats). Not bad at all.
