Knives used

Juggling is rarely performed with sharp knives, because there is little point in increasing the risk to performer for no aesthetic benefit. Specially balanced juggling knives are used, usually with a bevelled edge to appear sharp. Performing with genuine machetes is not generally advised because the spin and balance are unfavourable, and tricks beyond the basics become much more difficult. Various bladed implements ''can'' be juggled, but many have a dangerous and unpredictable spin as seen on an

While this makes knife juggling much safer than popularly assumed, knives can still cause severe trauma injuries to the head and body when falling from a height. Because of this, the juggling of large lumps of metal should only be attempted by competent club jugglers who understand the risks.
