To home in on something is to move towards it precisely, like a homing pigeon or a guided missile. To hone is to sharpen a blade or a skill. "Hone in on" is a very common error for "home in on" — though it is now so widespread that some dictionaries record it.
The core difference
A verb of targeting and a verb of sharpening.
- home in on — converge on a target: homed in on the problem.
- hone — sharpen: hone a knife, hone your skills.
Where "home in" comes from
From homing pigeons, and later homing devices and missiles — moving unerringly towards a destination. The metaphor is navigation, which is why home is the right word: you are heading somewhere.
Why "hone in" spread
Because hone suggests refining and narrowing, which feels close to what "homing in" describes. The confusion is semantically understandable rather than random, and that is why it has taken hold — but hone in is still flagged as an error by most editors.
