Aha, it turns out it's very picky about what type of sword will break it. I had tried with a mantis sword, a Felucco knife, light crab mace, and stone sword.... but a copper sword seems to do the trick. I don't think it makes much sense to require such a relatively high-level sword, considering it's.... string. :)
Also, I seem to have not obtained any string since clearing up my base.
They're all over my base and nothing can destroy them!
Use a sword to cut webs and get some free string in the process :)

Thanks so much for replying and maintaining this.
