Beautiful Swords And Knives

Ceremonial use
Swords are commonly worn as a ceremonial item in many military and naval services throughout the world. Occasions to wear swords include any event in dress uniforms where the rank-and-file carry arms: parades, reviews, tattoos, and changes of command. They are also commonly worn for officers' weddings, and when wearing dress uniforms to church—although they are rarely actually worn in the church itself.
In the British forces they are also worn for any appearance at Court. In the United States, every Naval officer at or above the rank of Lieutenant Commander is required to own a sword, which can be prescribed for any formal outdoor ceremonial occasion; they are normally worn for changes of command and parades. For some Navy parades, cutlasses are issued to Petty Officers and Chief Petty Officers.
