I know that there are more hook distributors than manufacturers. Who actually makes the hooks that we use?

I'm going to think that Mustad is an actual manufacturer. I'm looking for who makes which hooks. I know that there are different specs, but would love some kind of chart of who made the hook and who distributes their hooks with the names of the distributors.

If no such chart exists. Please add the examples that you are aware of. Thanks in advance.
