The safest way to store passwords is written down on a piece of paper. Maintain physical custody of it, never let it out of your possession.
If you need backups, use a non-networked copier, or an old style stand-alone point and shoot camera. Don't ever put the SD card in your computer. Keep all copies as secure as the original.
Banks have safety deposit boxes that can offer relative security. If you really want to be safe, manually encrypt your passwords.
[Edit] As others have pointed out, phishing is an issue. Be careful where you enter your passwords.
I prefer to avoid the word "safest" in this context without a specific threat model. Yours is likely different than mine, as I'd generally regard that method as less safe than a password manager. YMMV

This makes you vulnerable to phishing, and unwittingly entering the password on fake websites that mimic the real one.
Use a password manager with autofill on the correct URL.
