I was just having fun. I think the word ‘hones’ is considered to be above the 6th grade level. Probably a contributing factor to the authors misuse.
I sharpen a knife blade until it is ready to be honed. I then hone in on it until I have created an Euclidian plane.
A homing pigeon cares not what a Euclidian plane is. Nor do most people. Does a homing pigeon “hone in” on home, or does the homing pigeon “home in” on home?
dd, If you think the red thingies are neat, you should see the green thingies. I use both at Christmas time to create a light display amid the snow flakes. Nor do homing pigeons care about that.
