A ceremonial dagger

From MUME

!# C>exa dagger
The silvery blade is heavier and thicker than most daggers and is obviously 
ancient. Miniature carvings on its surface depict battles against a dark army,
resulting in the fall of Eregion. 

!# C>con dagger
It is a ceremonial dagger (flawless, new).
This piercing weapon can be wielded one-handed.
It is average while attacking and excellent while defending; its speed is very fast, and it inflicts average damage upon hitting.
It weighs about one pound.

Opinion

Probably the dagger that gives most defence bonus.
