Tool manufacturers include all kinds of annoying safety devices to attempt to prevent injury, or at least to give them some cover in a lawsuit.

Table saw blade guards and riving knives are an ironic example here: I've yet to hear a story of a woodworker that lost a finger on a table saw that wouldn't have been able to avoid that injury if they kept one of those safety devices on the saw. Everyone thinks the annoyance isn't worth it, since they are an 'expert', yet it happens frequently.
