The French estoc or English "tuck" was a type of European thrusting sword in use from the 14th to 17th centuries.
Unlike the rapier, which was used mostly in a civilian context, the estoc more resembles traditional swords with a crossguard mainly due to its use as a battlefield implement for getting into the chinks of armor.
