Weapon European repeatedly used, seizing power (4)

I believe the answer is:

epee

I'm a little stuck... Click here to teach me more about this clue!

'weapon' is the definition.
(I know that epee is a type of sword)

'european repeatedly used seizing power' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'repeatedly used seizing power' becomes 'pee' (I can't justify this - if you can you should give a lot more credence to this answer).
'e'+'pee'='EPEE'

Can you help me to learn more?

(Other definitions for epee that I've seen before include "piece of fencing" , "Sharp-pointed duelling sword" , "Fencing sword, heavier than a foil" , "Duelling blade" , "Bit of fencing" .)

I've seen this clue in The Guardian.
