High sea's extremely rough for clippers (6)
I believe the answer is:
shears
'clippers' is the definition.
(I've seen this before)
'high sea's extremely rough' is the wordplay.
'high' is an anagram indicator (can mean drunk or on drugs and hence disordered).
'extremely' suggests removing the centre.
'rough' with its middle removed is 'rh'.
'seas'+'rh'='seasrh'
'seasrh' with letters rearranged gives 'SHEARS'.
'for' acts as a link.
(Other definitions for shears that I've seen before include "Large clippers" , "Cutting tool, for hedges perhaps" , "Pruners" , "cutter" , "fractures under pressure" .)
