Sword Sites

Cheness Cutlery
Good economical swords. The stainless steel Iaito sword makes a pretty good substitute for a Korean saegum for forms practice. It is similar in weight and balance to a jingum.

MartialArtsSwords.com
Better quality swords.  The L6 jingum is a particularly nice for mat and bamboo cutting.
