How do jingums differ from katanas?

QUESTION: I am now interested in jingums. I just wonder how they are different from katanas. As far as I understand, the differences are the tip, the width, and the weight of the blade. With lighter and wider blade, a jingum can be wielded faster and can cut better than a katana. Is that correct?

ANSWER: Jimgums aren't really my strong point (at all) and I could be wrong with my answers here (I'm sure someone will correct me if I am off base).

But my understanding is that the Jingum's blade is thinner and wider as you note (a bit like 'competition cutters'), with a kissaki much like a Shobu Zukuri Katana and quite a style of fittings and it has less curvature than a Katana.

They definitely feel lighter than a Katana (usually around half a pound or more) and handle accordingly - though as to them being a better cutter or not, I'm not going there - wars have been fought for less..! Lol.
