Leader making a sharp point (9)
I believe the answer is:
spearhead
This clue is a double definition.
'leader' is the first definition.
(the leader of a project or plan)
'a sharp point' is the second definition.
(the point of a spear)
'making' is the link.
(Other definitions for spearhead that I've seen before include "Take the lead in" , "those at the forefront" , "Take charge of" , "Lead (an attack or movement)" , "Lead (a military attack)" .)
