Untidy dagger bled out of control (10)
I believe the answer is:
bedraggled
'untidy' is the definition.
(thesaurus)
'dagger bled out of control' is the wordplay.
'out of control' indicates an anagram.
'dagger'+'bled'='daggerbled'
'daggerbled' is an anagram of 'BEDRAGGLED'.
(Other definitions for bedraggled that I've seen before include "Unkempt" , "muddy and dripping" , "Wet and dirty" , "Very untidy" , "Dishevelled" .)
