The AFTCO Circuit Breaker was specifically developed for the Shinkei Jime technique and is used to precisely sever a fish’s spinal canal and completely stun it. This reduces uncontrolled muscle movements and the release of stress hormones, which can have a positive effect on the color, texture, and shelf life of the meat. The memory-resistant wire material retains its shape even after frequent use and does not kink. Thanks to its lightweight, single-strand design, the Circuit Breaker is easy to handle and clean. It is available in various gauges and lengths and can therefore be adapted to different fish sizes.
