| On the right is shown a proposal for a more sophisticated design of the Sasumata or Catchpole, based on a medieval German example and combining the features of both Sasumata and Tsukubô.|
Section A can be used to capture a suspect's arm or leg and has sprung jaws to prevent them freeing themselves. Once a limb is gripped the pole can be rotated and manipulated to apply a lock or control a suspect. The shaft might be fitted with side handles and the butt with a T-grip to facilitate this.
Section B can be applied to a broader target such as the torso to pin the suspect against a wall or hold them down on the ground. This section may have some padding to reduce the possibility of bruising.
Section C is a hook that can be used to pull or trip a suspect.
Variants of the Catchpole would include a telescopic or sectioned version that can be carried in the trunk of a police car.
