Took it outside; left with the carpenters’ things (4,3)

I believe the answer is:

tool kit

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

'the carpenters' things' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'took it outside left' is the wordplay.
'outside' means one lot of letters goes inside another.
'left' becomes 'l' (common abbreviation).
'took'+'it'='tookit'
'tookit' placed around 'l' is 'TOOL KIT'.

'with' is the link.
