Kamayari in Japanese Katana terminology
What is Kamayari in Japanese Katana terminology?
"Kamayari" (鎌槍) refers to a type of spear that has a sickle-like blade protruding from part of the spearhead (the blade of the spear). This design is intended to prevent the spear from penetrating too deeply into the opponent and becoming stuck. If the sickle-like blade is only on one side, it is called "Katakamayari" (片鎌槍). If there are sickle-like blades on both sides, it is called "Ryokamayari" (両鎌槍).
