Let me see explosive fur (6)
I believe the answer is:
ermine
'fur' is the definition.
(I know that ermine is a type of fur)
'let me see explosive' is the wordplay.
'let me see' becomes 'er' (both might be said when hesitating).
'explosive' becomes 'mine' (e.g. a landmine).
'er'+'mine'='ERMINE'
(Other definitions for ermine that I've seen before include "Ceremonial fur" , "Stoat's winter fur" , "'Trimming on royal robes, say (6)'" , "Expensive white fur" , "Fur for an English judge" .)
