Tools passed up the wall (6)

Ross

I believe the answer is:

spades

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

'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" .)

I've seen this clue in The Telegraph.
