Kenzan
A kenzan, also called spiky frog, is a specific device used in the Japanese art of flower arrangement ikebana for fixing the flowers in the container. It consists of a heavy lead plate with erected brass needles where the stipes are fixed.
The name kenzan literally means sword mountain. It was introduced by the Moribana style of ikebana.
In some ultraviolent wrestling promotions like BJW, CZW and GCW, kenzans are used as weapons, usually planting them to head.
