Hmm, on second glance, there are
at least ten-ish inanimate object examples in the list, which isn't unreasonable—it would be enough to launch it if it were a YKTTW
draft. I can buy that as distinction as tropable, or at least open for discussion as such. (There's nonlethal (single-limb) examples too, but I consider those a textbook case of a Downplayed Trope
—it's fundamentally the same tactic, just on a smaller scale. Very easily lumpable.)
Looking at some of the related tropes, it's possible that it's merely suffering from a lack of proper crosswicking. Literally Shattered Lives
and Kill It with Ice
are very closely related, but they lack cross-referencing. Most of the examples on the page aren't crosswicked either.
I am not at all worried about the name being mistaken for the idiomatic conversational usage. The meaning should be very clear from the context.
