So how do you (tech savvy) guys save your important keys?

Whenever someone loses funds, lots of people say that's not how to store your keys. They can be compromised easily in that setup. Just wondering what the correct way is in that case.

I remember reading the Winkle twins had parts of their keys on paper in multiple locations. And had multiple copies of this setup. No idea if this is the way (practically, for a small hodler like me, it would mean half key on paper, half key in encrypted files in offline drives.) Is this any good?

What is the correct, safest way to store seeds/phrases/keys?
