Smoking is bad for you.

Yes it is.

Depends on what the "plastic" is.
Many kinds of hi-strength line don't melt unless you get the temp much
much higher. It's rather frustrating because they need an old-
fashioned whipped end instead of just neatly melting it.

Yes. some while ago when I first had experience with a kevlar rope I was
surprised that my electric cutting knife made no impression on it at all. I
had to saw it through with a serrated edged knife and even that took some
time.
