Knob and Tube wiring is safe if:
the original wiring was properly installed
it has not deteriorated & is properly maintained
no new or extra outlets and plugs have been added
it was not tempered with during house upgrades & repairs
it is not overloaded & protected with a 15 Amp fuse or breaker
all three prong wall plugs on K&T circuits should be GFCI protected
Most houses with Knob and Tube would have one or more conditions inconsistent with the list above
