Maguro kiri bōchō – video |Bluefin Tuna|

Tuna’s quarter is cut with the swordsmanship you’d expect only from Japanese. The video speaks for itself and the knife is named Maguro kiri bōchō. The maguro bōchō is a 150 cm long. They fillet a tuna in a single cut, and the flexible blade is curved to the shape of the spine to minimize the amount of meat remaining on the tuna carcass.
