Mr Martin died when one of his major heart blood vessels was cut.
Kelly told the court he acted in self-defence.
Judge Christopher Moss said to Kelly: "You had lost your self-control by reason of provocation.
"Your use of the sword was quite deliberate."
Note the use of the word 'samurai' in this piece's header.
While this may be seen as fodder for the ban the sword lobby (see the Mail article below) I see it more of a case to keep one's level-headedness and cool approach to conflict. Don't lose your cool! (or bring out the 'samurai sword' to settle domestics...!)
Whilst digging around for references to this article I came across another sword related death. This time (unsurprisingly in the Daily Mail) more samurai scare-mongering over this sword. Samurai sword mentioned in headline and in the image caption.
This is the sword.
