Duri Noko

The Durinoko are the weapons Kamen Rider Blavo uses in his Durian Arms, consisting of a pair of broadswords with serrated edges on the blades, as well as spikes on what would be the flat of the blades, with the tips of the blades near-shovel like in design.

Trivia

 * Like the Ichigo Kunai, this Lockseed weapon comes in multiples. It shares this trait with Kiwi Arms' chakram weapons that also come in a pair.
