By the sound of it, everyone’s hand tool (3)
I believe the answer is:
awl
'hand tool' is the definition.
(awl is a kind of hand tool)
'by the sound of it everyone's' is the wordplay.
'by the sound of it' shows a homophone (sound like).
'everyone' becomes 'all' (I've seen this before).
'all' is a homophone of 'AWL'.
(Other definitions for awl that I've seen before include "Sharp point" , "it may be piercing" , "has its use at last" , "Pointed tool for punching holes" , "It bores" .)
