Implement obtained from second squalid home (6)
I believe the answer is:
shovel
'implement' is the definition.
(shovel is a kind of implement)
'second squalid home' is the wordplay.
'second' becomes 's' (common abbreviation).
'squalid home' becomes 'hovel' (a hovel is a dirty or squalid building).
's'+'hovel'='SHOVEL'
'obtained from' acts as a link.
(Other definitions for shovel that I've seen before include "Digging implement" , "Hand tool" , "Excavator" , "Tool to be found in hovels?" , "Scooper" .)
