a type of sword, and a comparison of the emblazons showed that the visual resemblance was overwhelming
A form of long, rigid, pointed, triangular or square bladed and virtually edgeless longsword designed for thrusting into plate-armor was the estoc. Called a "stocco" in Italian and a "tuck" in English, they were used with two hands - similar to great-swords. They were used in two hands with the second hand often gripping the blade. Rapiers are sometimes mistakenly referred to as tucks, and may have been referred to as such by the English.
The French estoc or English "tuck" was a variation of the longsword focused intensely on fighting against mail or plate armour.Tarassuk, Leonid & Blair, Claude. The Complete Encylopedia of Arms & Weapons. Simon and Schuster, 1982.
