Yes. But also a fencing sword would collapse that well and wold be useless against Romulans or pretty much anyone else.
(paragraph written by the original question-writer) Assuming I'm understanding your response fully, you site technical problems collapsing a rapier even though they can collapse a katana? Seems a dubious reason to me. Also, a modern katana would have been just as useless against the Romulan's weapon. Katanas (traditional ones at least) are not made for blocking attacks; to do so would break your katana. Rapiers, however, are designed for parrying (deflecting) blows away. And if a "future" katana can be made to block blows from a heavy weapon as heavy as the Romulan's, why not "future" rapiers made to do the same? Just seems odd to me a trained fencer would use the wrong tool for his trade.
