There is a short set involving this weapon or something closely related to it. There’s a great deal of spinning of the weapon along its long axis – some melons are going to experience satori or something in order to determine if the weapon has much offensive cutting power when it is spinning. To be sure, there’s plenty of damage that can be done stabbing with a point while both hands are in the handle area. Similarly, with two hands working a slash with one of the ends could be quite vicious. On the other hand, so as to speak, while the two small crescent blades make a defensive contribution, it is not so obvious that they are much of a threat even in a clinch. Maybe simple triangles would be more threatening – and deadly.
