Sword Dimensions - Iaito

We keep a record of key weights and measurements of various production katana. These are helpful in determining how different katana compare to ones you may be familiar with. Most katana are hand-made and the dimensions vary from sword to sword. These measurements were taken on a single sample and yours may vary from them. We also have Shinken (cutting sword) dimensions.
