I don't believe anyone in the history of the world has ever been killed with a string trimmer or as the result of the use thereof? Never been a Texas string trimmer massacre. About the worst string trimmer accident I'm aware of is a thrown rock breaking a window, or perhaps some busted up vinyl siding? Now, put a blade on the end, call it a brush cutter and then we have some potential... At least some gory leg injuries. But alas the humble string trimmer just isn't dangerous enough to garner the attention of a whirring razor sharp chain.
Now, if you organize a string trimmer get together, count me in.
