Removes edge or edges of blueprints (6)

I believe the answer is:

blunts

'removes edge' is the definition.
(removes a sharp edge)

'edges of blueprints' is the wordplay.
'edges of' says to hollow out the word (remove centre letters).
'blueprints' with its middle taken out is 'BLUNTS'.

'or' is the link.

(Another definition for blunts that I've seen is " Makes dull, takes the edge off".)

I've seen this clue in The Guardian.
