What is the "nagasa"

Thanks

It's the distance of the actual blade, not counting the handle.

Go to google and look for "Richard Stein's Japanese Sword Index". More info than you can shake a stick at.

Thanks Guys!

Nagasa simply means the length of something. Its not sword terminology.

Yup, like Hyaku said,

It's general Japanese. 'Nagasa' denotes the overall length of an object. It's not a term solely used in budo circles.
