Knife juggling is a variant of toss juggling using special knives which are thrown and caught. Although knives are sometimes juggled recreationally, it is generally a performance art. Knife juggling is typically seen performed by street entertainers as part of a routine.

Knife juggling is identical to club juggling in technique, consisting of throwing the clubs/knives upwards individually and then throwing and catching in a rhythmic pattern, usually with the objects crossing from hand to hand. The knives are thrown with vertical spin, lending them stability in the air, and are typically allowed to rotate once or twice before being caught. Knife juggling can, of course, be performed with any number of objects, but the vast majority of performers use three knives. Patterns used tend to be basic, or often consist solely of a cascade, the simplest of juggling tricks. This is partly due the unwieldy nature and increased weight of knives compared to clubs for juggling. Also, the performer is wary of spinning the knife incorrectly and thus catching the wrong end. Although this is perfectly safe with standard juggling knives it is to be avoided as it shatters the audience impression of severe risk.

Toss juggling is the form of juggling which is most recognisable as 'juggling'. Toss juggling can be used as: a performing art, a sport, a form of exercise, as meditation, a recreational pursuit or hobby.

In toss juggling, objects — such as balls, bean bags, rings, clubs, etc. — are thrown or tossed into the air and caught. Toss juggling is a form of object manipulation.

A sword is a bladed weapon (edged weapon) used primarily for cutting or thrusting. The precise definition of the term varies with the historical epoch or the geographical region under consideration. A sword in the most narrow sense consists of a straight blade with two edges and a hilt. However, in nearly every case, the term may also be used to refer to weapons with a single edge (backsword).

The word sword comes from the Old English sweord, cognate to swert, Old Norse sverð, from a Proto-Indo-European root *swer- "to wound, to cut". Non-European weapons called "sword" include single-edged weapons such as the Middle Eastern saif, the Chinese dao and the related Japanese katana. The Chinese jian is an example of a non-European double-edged sword, like the European models derived from the double-edged Iron Age sword.
