Its 2 main skills are mediocre at best. Health +20 can be easily gotten with food and Defense Up does not reduce damage much. You're much better off getting armors with better skills and upgrading them with Armor Spheres.
Speed sharpening and stamina theif are great skills, imo. Also, defense is the most underrated stat in the game. I agree that the health is worthless, and there are better armors, but tetsu is a good first g rank set imo. Especially to learn new attack patterns in g rank.
Edit: missed your previous reply, much better way of saying it.
