The handle of a sword is commonly referred to as the "hilt." The hilt is the part of the sword that provides a grip for the wielder's hand and connects the blade to the pommel. It is an essential component of the sword's overall structure and functionality.

The hilt typically consists of several elements, including:

1. Grip: The grip is the part of the hilt that the wielder holds onto during combat. It is usually covered with a wrapping material, such as leather, cord, or fabric, to provide a secure and comfortable grip.
2. Guard: The guard, also known as the handguard or crossguard, is a protective component situated between the blade and the grip. It serves to prevent the opponent's blade from sliding down and making contact with the wielder's hand. Guards come in various shapes and designs, ranging from simple straight crossguards to elaborate and ornate forms.
3. Pommel: The pommel is located at the end of the hilt, opposite the blade. It serves as a counterweight to the blade, helping to balance the sword. Pommels can vary in shape and size, from simple rounded or cylindrical forms to more decorative or intricate designs.

The hilt is designed to provide a secure and comfortable grip while allowing the wielder to control and manipulate the sword effectively during combat. It plays a crucial role in ensuring the wielder's safety, balance, and control while wielding the weapon.

It's worth noting that the hilt may also include other elements such as decorative fittings, ornamentation, or additional components depending on the specific sword design, cultural tradition, or historical period.
