Curse that combination bottle opener and salt shaker! (5)
I believe the answer is:
blast
'curse that combination' is the definition.
'blast' can be an answer for 'curse' (thesaurus). I am not certain of the remainder of the definition.
'bottle opener and salt shaker' is the wordplay.
'opener' says to take the initial letters.
'and' is a charade indicator (letters next to each other).
'salt shaker' becomes 'last' (I can't explain this - if you can you should believe this answer much more).
The initial letter of 'bottle' is 'b'.
'b'+'last'='BLAST'
Can you help me to learn more?
(Other definitions for blast that I've seen before include "Blow up or swear" , "Noise of explosion" , "Strong gust of air" , "Damn - explosion" , "Effect of explosion" .)
