I have a matched set of Japanese swords (Katana and Wakisashi) in a rack over my TV. They were made the "old" way using folded steel and different grades and hardness steels. The blades are not polished (working blades!) but are razor sharp. They are great self defense weapons, quiet and efficient! If anyone broke into my house and got by the 150 lb Great Pyr, they would have to deal with a deadly blade in the hands of someone trained to use a sword. Don't have to worry about it accidentally penetrating a wall either! Just for the record, a Sig P220 would be the backup to the Katana!
