A dagger is a fighting
knife
A knife ( : knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evide ...
with a very sharp point and usually two sharp edges, typically designed or capable of being used as a thrusting or
stabbing weapon.
[State v. Martin, 633 S.W.2d 80 (Mo. 1982): This is the dictionary or popular-use definition of a dagger, which has been used to describe everything from an ice pick to a folding knife with pointed blade as a 'dagger'. The Missouri Supreme Court used the popular definition of 'dagger' found in Webster's New Universal Dictionary ("a short weapon with a sharp point used for stabbing") to rule that an ordinary pointed knife with four-to-five inch blade constitutes a 'dagger' under the Missouri criminal code.][California Penal Code 12020(a)(24):"dagger" means a ''knife or other instrument'' with or without a handguard that is ''capable of ready use as a stabbing weapon'' that may inflict great bodily injury or death. The State of California and other jurisdictions have seized upon the popular-use definition of a dagger to classify items ranging from a pointed kitchen knife to a tent stake as a 'dagger' under the law.] Daggers have been used throughout human history for
close combat confrontations, and many cultures have used adorned daggers in ritual and ceremonial contexts. The distinctive shape and historic usage of the dagger have made it iconic and symbolic. A dagger in the modern sense is a weapon designed for close-proximity combat or self-defense; due to its use in historic weapon assemblages, it has associations with assassination and murders. Double-edged knives, however, play different sorts of roles in different social contexts.
A wide variety of thrusting knives have been described as daggers, including knives that feature only a single cutting edge, such as the European
rondel dagger or the Afghan
pesh-kabz, or, in some instances, no cutting edge at all, such as the
stiletto
A stiletto () is a knife or dagger with a long slender blade and needle-like point, primarily intended as a stabbing weapon.Limburg, Peter R., ''What's In The Names Of Antique Weapons'', Coward, McCann & Geoghegan, , (1973), pp. 77-78

of the Renaissance. However, in the last hundred years or so, in most contexts, a dagger 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.
