Article not entirely nasty? It gets a hammering (5)
I believe the answer is:
anvil
'it gets a hammering' is the definition.
(an anvil is hammered by a blacksmith)
'article not entirely nasty?' is the wordplay.
'article' becomes 'an' (indefinite article).
'not entirely' means to remove the last letter.
'nasty?' becomes 'vile' ('vile' can be a synonym of 'nasty').
'vile' with its last letter taken off is 'vil'.
'an'+'vil'='ANVIL'
(Other definitions for anvil that I've seen before include "Metalworker's block" , "Heavy block on which to hammer metal" , "One frequently gets hammered" , "One getting hammered regularly" , "Block on which metal can be hammered" .)
