My father tells me that he spent some time as a central heating boilerman in Leningrad. Now, boilermen worked in the basements of appartment buildings, and because gas boilers were used, they had to do very little actual work - just sit there and wat the boiler.
For some strange reason, my father tells me they were issued a torch about like the one you linked - just a longer tube that made a small, but very visible flame on one end. He explained - but I do not remember - the purpose of this contraption.
And so what happened was that one day, a group of thug-like young people knocked on the boiler room door and demanded my father open the door and give them cigarettes.
The door opens slightly, and an angry-looking dude with a huge black moustache appears, holding a torch in one hand, the flame turned up.
"Good day," my father asks, "How may I help you?"
Thug: "Uh... nevermind. Nevermind."
At which point they parted happily.
