Rapier generally refers to a relatively long-bladed sword characterized by a complex hilt which is constructed to provide protection for the hand wielding it. While the blade might be broad enough to cut to some degree, the strength of the rapier is its ability as a thrusting weapon. The blade might be sharpened along its entire length, sharpened only from the center to the tip (as described by Capoferro), or completely without a cutting edge as called "estoc" by Pallavicini, a rapier master who, in 1670, strongly advocated using a weapon with two cutting edges. A typical example would have a relatively long and slender blade of 2.5 centimetres or less in width, 1 meter or more in length and ending in a sharply pointed tip.
