How to fix commodity content for clients?

By now it’s clear that Google dislikes commodity (skyscraped?) content, and prefers unique info and perspective. (Links are not permitted in the subreddit so can’t link sources)

The principle itself is clear, but the practice isn’t.

For example, let’s say the client sells hammers.

“Boring” topic, all top ranking sites are optimized to death, and since it’s a client, you can’t bring your own unique POV into the content.

Also the clients usually don’t give extra info or input, they pay for the problem to be solved (99% of them in my case).

What would you do then? (hammers are just random example, feel free to choose anything else)
