Our Double ended Thin Stick is probable the most used. They are very much like the real rataan sticks. The Double ended can be disarmed and returned using the other end.
For more realism, we make the Thin Stick w/Handle. These feel like a real stick, but can't be returned using the Handle end without using "Control" on the return!
We like to use the Nylon core for heavy bag work. It also serves as a great "Self Defense" baton, instead of a real stick.
