Leatherworking tool (3)
I believe the answer is:
awl
'leatherworking tool' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for awl that I've seen before include "Pointed tool for punching holes" , "Borer, sounds like everything" , "One piercing" , "Instrument for boring holes" , "a boring person needs" .)
