In-game description
"Katana +2: Malakar This sleek katana radiates magical energy when carried. The Malakar, or 'Dueling Steel', was used by a less-than-honorable samurai during duels against other samurai. As if of its own volition it will swoop down and deflect the slashing attacks of other weapons. It is perfect for the warrior concerned about defense as well as offense."
