That was part of my thinking when I answered as well.
I got the cold steel "1917 Cutlass" as a gift. It is pretty nice! But, like most Cold Steel products it is way, way heavier than it needs to be.
It is a cut-and-thrust sword like you mentioned in your original post. It has a 25" blade, so it is relatively short. It is a "mere" 34oz. You feel that weight when you move it.
In a hallway, it is awful. It is too heavy to be fast on the thrust. The blade geometry works for thrusting, but it isn't "fast". Fast is what you need for a thrust.
And when you swing it (much like a bat =) ), you are telegraphing like mad. In tight quarters, you can't get velocity early to make it count if you get rushed.
If they made the blade 22" long, and 12oz lighter, it would be damn good. But, CS really goes for the "can I pry manhole covers up with this??" market, maybe because overbuilding with inexpensive steel means they need less QA to put out a product that doesn't break.
