Hole puncher (3)
I believe the answer is:
awl
'hole puncher' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for awl that I've seen before include "Law about a drilling tool" , "Pointed tool for punching holes" , "It bores" , "Pointed instrument" , "Borer, sounds like everything" .)
