Pull no punches

Over the top

Over the counter

Open old wounds

Open old sores

Pull no punches

Over the top

Over the counter

Open old wounds

Open old sores

On hold

Olive branch

Oldest trick in the book

Old wive’s tale

Old hat

Old friends and old wine are best

Old flames die hard

Old chestnut

Not worth a tinker’s dam

No holds barred

Newfangled

New brush sweeps clean

Money for old rope

Long in the tooth

Lo and behold

Let sleeping dogs lie

Let bygones be bygones

Know where all the bodies are buried

Kill the goose that lays the golden egg

Good as gold

Golden touch

Golden rule

Golden handshake

Go under the hammer

Go down like a cup of cold sick
