Estoc blades are a form of sword, which can also be called "tuck" or "armor piercers" in some regions. With a large, pointed appearance, they can often look similar to an oversized dagger. These swords use a slim blade, attached to a hilt that is large enough to hold with both hands. To protect the wielder, a hefty crossguard is also installed on the sword. Beginning in the 15th century, Estoc blades became a popular choice for combat. Their slender, precise design made them excellent at exploiting weaknesses in enemy armor. From grand tournaments to heated battlefields, this sword was used widely across various forms of combat.
