The French estoc is a type of sword, also called a tuck in English, in use from the 14th to the 17th century.[1] It is characterized by a cruciform hilt with a grip for two-handed use[citation needed] and a straight, edgeless, but sharply pointed blade around 36 to 52 in (91 to 132 cm) in length. It is noted for its ability to pierce mail armor.
