Here's a question that has been on my mind, lately... Should a katana have a distal taper? logically, I'd assume so, but I have no idea if they do traditionally, or not.
For the most part, yes. Both in blade and tang. When looked at overall, blade is a long, skinny diamond shape on all sides. Despite what people say, there's no hard rules to all this, can have no distal taper if wanted and there are antique examples of this.
