After end of training I am allowed a tool (6)
I believe the answer is:
gimlet
'a tool' is the definition.
(gimlet is a kind of tool)
'after end of training i am allowed' is the wordplay.
'after' means one lot of letters go next to another.
'end of' indicates one should take the final letters.
'i am' becomes 'im'.
'allowed' becomes 'let' (I've seen this before).
The last letter of 'training' is 'g'.
'g' next to 'im' is 'gim'.
'gim'+'let'='GIMLET'
(Other definitions for gimlet that I've seen before include "Wood-boring tool" , "One pierces" , "Hole borer" , "Hole-boring tool" , "Hand tool for boring holes" .)
