I believe the answer is:

bottle opener

I'm a little stuck... Click here to teach me more about this clue!

'levering device' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'pole no better used' is the wordplay.
'used' is an anagram indicator.
'pole'+'no'+'better'='polenobetter'
'polenobetter' anagrammed gives 'BOTTLE-OPENER'.

'for' is the link.

Can you help me to learn more?

(Other definitions for bottle opener that I've seen before include "Device for removing caps and corks" , "access to 'beer'?" , "Prising implement" , "Kitchen/bar tool" , "Cap remover" .)

I've seen this clue in The Telegraph.
