Bind: An attack which engages the opponent's blade and moves it diagonally to the opposite quadrant (i.e. from the inside high to the outside low, or outside high to inside low, etc.). A liement.
Prise [de Fer] (Fr.: "taking the iron"): A "taking" or contacting of the opponent's blade in an offensive or counter-offensive action; taking the blade. (Pronounced "pree-z [deh fair]")
Normally (in foil, at least, the only weapon with which I'm very familiar) you try to get around the guard, in this move, you literally push your opponents blade into a new position and then (in theory anyway) follow this move up with a quick lunge to the now open quadrant. We learned this second semester in college fencing.
By the way, is it hard to hook up with local fencing groups? I'd love to get back into it, and learn saber as well.
