Dagger

A dagger is a knife with a very sharp point designed or capable of being used as a thrusting or stabbing weapon. The design dates to human prehistory, and daggers have been used throughout human experience to the modern day in close combat confrontations. Many ancient cultures used adorned daggers in ritual and ceremonial purposes, a trend which continues to the present time in the form of art knives. The distinctive shape and historic usage of the dagger have made it iconic and symbolic.

Over the years, the term has been used to describe a wide variety of thrusting knives, including knives that feature only a single cutting edge, such as the European rondel dagger or the Persian pesh-kabz, or, in some instances, no cutting edge at all, such as the stiletto of the Renaissance. However, over the last hundred years or so, authorities have recognized that the dagger, in its contemporary or mature form, has certain definable characteristics, including a short blade with a sharply tapered point, a central spine or fuller, and (usually) two cutting edges sharpened the full length of the blade, or nearly so.

Cloak and Dagger (comics)

Cloak (Tyrone "Ty" Johnson) and Dagger (Tandy Bowen) are a fictional comic book superhero duo appearing in American comic books published by Marvel Comics. They were created by writer William "Bill" Mantlo and artist Edward Hannigan.

Concept and creation

The inspiration for Cloak and Dagger came to Bill Mantlo after a visit to Ellis Island. He recounted, "They came in the night, when all was silent and my mind was blank. They came completely conceived as to their powers and attributes, their origin and motivation. They embodied between them all that fear and misery, hunger and longing that had haunted me on Ellis Island."

Ed Hannigan, Mantlo's artist collaborator on Peter Parker, the Spectacular Spider-Man, recalled that he and Mantlo jointly came up with the characters' visual design: "Bill had a short page or two synopsis of the story that he showed me, and we discussed what the characters would look like. He gave me a lot of leeway, but it was fairly obvious that Cloak would be black and have a big ‘animated’ black cloak and Dagger would be white with a skintight leotard-type thing. I am not sure, but I think I might have come up with her ballet angle. I put the same kind of amulet/clasp on both costumes and came up with the dagger-shaped cutout on her costume, which was quite daring at the time."
