One of the oldest and most respected, Sword Forum International (SFI)
was designed to showcase and discuss the works of various custom sword
smiths, but has over the years branched out to encompass ALL types of
swords although the focus is on custom and antique swords.
This site has many sword tests and reviews. If you are thinking about buying your first sword this is a great place to start. This website however is focused towards low end production swords.
