'protection' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'deburring metal is mandatory' is the wordplay.
'TALISMAN' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.

'when' is the link.

Can you help me to learn more?
