today I used it to hold my generator in the bucket so I could raise it up to a good height to work on.
Tomorrow it will be to lift my CUB so I can get at the blades to sharpen them.
Last week I used it to run a chain to my 'tongs' to lift some logs.
Previous week I used them (2 of them) to hold a large stump in the bucket I dug up.
In a week of so I'll be moving some granite slabs that I use for my back steps.
I have used it to lift and lower a couple of engines in and out of cars and a boat.
I've used them to hold up logs to be able to cut them off of the ground.
I've put clamp on forks on my loader and used the hooks to hold chains to hold the load on the forks.
I pick up my rear blade and move it around the barn using a chain on the bucket hook.
I've picked up tractor tires by hooking a chain on the bucket and thru the hole in the wheel.
A few days ago I chained a stove in the bucket so I could move it over to the dumpster to destroy it.

there's more, I'm sure.
I have 3 of Ken's bolt ons on my fel bucket and one on each of my bh buckets.
If you can't think of a reason for a hook on the bucket, you either have no imagination or don't need a bucket.
