Crystal Katana of Woo
From Discworld MUD Wiki
Judge result: You determine that the Crystal Katana of Woo is not a melee weapon.
This katana looks very impressive indeed. A thin, curved blade apparently composed of glimmering crystal gleams dangerously, and widens as it approaches the silver hilt. A large glittering ruby adorns the pommel. Unfortunately, as impressive as the sword looks, the crystal blade is so delicate that it's doubtful you could chop celery with it. It's shiny and expensive, though, and that's the main thing. It's also not very old, but it will probably become an ancient heirloom eventually.
The Crystal Katana of Woo is about three feet long and a couple of inches wide. It is made of crystal.
