Serpentine dagger

The Serpentine Dagger is a specialty of the Library of Scars in Jhelom, who have many serpent-like weapons in their arsenal. While it does not do any more damage than a normal Dagger, exactly 1, it is seen as a status symbol by the members of the guild.

During Ultima VII, the Avatar found one of these daggers at the murder site in Minoc and confronted Master DeSnel of the Library of Scars about it, proving that it was one of their daggers. DeSnel recognised the dagger as the one he'd given Hook as a gift and, seeing that his cover was blown, attacked the Avatar. In that battle, Desnel died.

Trivia

 * Serpentine Daggers of course also exist on the Serpent Isle, where they were heavily used by the old Ophidian culture.
