It is simply a club which, instead of the usual bell end, has a (usually non-asbestos) flame proof wick screwed or bolted on to a metal sheath. The torch is lit by dipping the wick in fuel and the fuel then burns without damaging the wick (in principle).
This section, then, is on the use of torches: what they are, how to use them (safely), what to use for fuel, how to make colored flames, etc. There's no info on brands to buy or fancy tricks (yet). Thanks to Ken Zetie, who originally wrote all this.
