Howling:Is the sonic cane really that useful?

The sonic cane seen in lets kill hitler. Would it really be useful as the doctors replacement instead of the screwdriver. It is very bulky and would be difficult to use in tight spaces. If the doctor was captured, the cane would be instantly confiscated whereas the screwdriver could remain hidden. That said, it would probably only be inconspicuous in the hands of first doctor or a doctor who wore similar clothing to the 11th doctor in that scene such as a top hat and tuxedo. Someone like the ninth or fourth doctors for an example wouldn't be able to pull one off without looking odd(well odder than usual)I like the idea but it just wouldn't be very practical. --Coop3 ☎  20:35, July 1, 2013 (UTC)
