A friend brought in a 57.8" overall length nodachi for me to test its performance. I did not modify the edge geometry but sharpened the apex with the factory angle. It did cut through ok but with lots of resistance as a result. The tremendous blade length at 46" with only 11.8" hilt, plus being a narrow tsuka and lack of distal taper, rendered it very forward heavy and proned to rotate inside the grip. Edge holding ability is so-so as well. Overall this is a piece of work that needed some fine tuning to become stellar in performance.
