Épée
Épée is the one where you can't bluff. Whole body is target, no right of way, first hit wins. Patient fencers love it. Impulsive fencers learn discipline from it.
The thinker's weapon.
There is no right of way in épée. There is no 'who attacked first.' There is only the question of whose blade arrived. The patience this demands — the ability to wait, probe, and commit only when committed is correct — is what separates good épéeists from great ones.
Equipment
Épée is the heaviest of the three weapons — up to 770 grams, compared to roughly 500 for foil and sabre — and the stiffest. The whole body is target, head to toe, and there's no priority rule. If both fencers hit within 1/25th of a second, both score. The weapon decides.
What that produces is a tactical, patient style. Top épéeists are chess players: they probe, set up, wait for the right opening, and only commit when the math is right. This is the weapon coaches recommend to fencers who think before they move.
It's also the great equalizer. Foil and sabre reward speed. Épée rewards reading the opponent. A fifty-year-old who's been fencing for two decades can still beat a twenty-year-old phenom.
