Handheld Torch, cutter?? Propane?

[Alex van de Wetering]

I have been trying to find out more about the handheld torches sometimes seen in car restorations (heating up nuts/bolts, bending sheet metal). They are roughly the size of a grease gun, with a similar curved neck and they seem to use a small cannister of gas (acetylene? propane?).
The advantage is that you don't need two huge gas cilinders as used in a normal acetylene torch....and therefor seem ideal to heat up bolts in a rusty CMP.

Sadly I can't seem to find them here in Holland,

Does anyone know of any manufacurers of supplier names, which culd help me in my search?
