A 'second' in ancient Japanese culture. This person would act on behalf of the Shogunate. This would be an executioner who decapitates men after they have performed ritualistic suicide (Seppuko).
An example of this is the character Ogami Itto in the film series 'Lone Wolf and Cub'. He was chief executioner and would behead disgraced samurai with one fell swoop of his dotanuki.
His sword is a dotanuki, as used by the Shogun's Kaishaku (second). This must be Ogami Itto.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
