Tools passed up the wall (6)
I believe the answer is:
spades
'tools' is the definition.
(spade is a kind of tool)
'passed up the wall' is the wordplay.
'passed' can be anagrammed to 'SPADES'.
However, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for spades that I've seen before include "Suit in pack of cards" , "Passed around with diggers" , "Digging tools and card suit" , "Card suits and shovels" , "Does some groundwork" .)
