A tool to suit Len, perhaps (7)
I believe the answer is:
utensil
'a tool' is the definition.
(I've seen this before)
'suit len perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'suit'+'len'='suitlen'
'suitlen' with letters rearranged gives 'UTENSIL'.
'to' is the link.
(Other definitions for utensil that I've seen before include "E.g. colander" , "Tool for practical use" , "Can opener, for example" , "Containers for kitchen use" , "vessel" .)
