I believe the answer is:
awls
'leatherworker's tools' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for awls that I've seen before include "Small piercing tools" , "Tools for punching small holes" , "Laws about boring tools (4)" , "Pointed hand-tools" .)
