A rapier or espada ropera is a type of sword with a slender and sharply pointed two-edged blade that was popular both for civilian use (dueling and self-defense) and military use. Rapiers are typically narrow blades (from edge to edge) and don't have much weight behind them. As such, to cause much damage from a cut, you have to perform the cut properly.
The rapier line is a nod to those great players who played with such grace and elegance. Watching them pull off game breaking moves or even simply move from bunker to bunker was like watching an elegant dance or fencing match. These players played with such pure form you rarely understood what happened to you and your team as you were walking off the field in awe. Players like this were inspiring to watch and even secretly root for. The Rapier line reflects these players’ style in a bright and expressive yet very clean headband.
