Old friend seizes equipment for paper manipulation (7)
I believe the answer is:
origami
'paper manipulation' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'paper' relates to this answer.
'old friend seizes equipment' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'friend' becomes 'ami' (I've seen this before).
'seizes' is an insertion indicator.
'equipment' becomes 'rig' (rig is a kind of equipment).
'o'+'ami'='oami'
'oami' placed around 'rig' is 'ORIGAMI'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for origami that I've seen before include "Paperwork, as it were" , "Artwork with paper" , "US record label" , "Delicate operations" , "folding stuff?" .)
