'''Sword grass''' is a name used for some species of [[Poaceae|grasses]] with blades that are sharp enough to cut human skin. This is because they contain many [[silica]] [[phytolith]]s, a hardening material in many plants. The sharp blades help to discourage herbivores from grazing, protecting the grasses around it as well.
