Usage: Hone or Home In?

It’s quite easy to confuse these two words, especially since they sound so alike in casual speech.

You home in when you’re getting close to home.
You hone your skills with practice, so you never actually hone in for or at anything.

Trick to Remember
Do you feel like a homing pigeon? Then you’re homing in.
Have you sharpened your skills? Then you’ve carved away part of that m in home and are left with hone.
