The new torches have flashback arrestors. The old ones don't.
However, it hasn't ever seemed to be an issue for me.\
I suppose, like a seat belt, you don't need it, until you really NEED it.
Maybe I am wrong. But the arrestor's attach where the gas enters the handle. They do not prevent burning in the handle. Old Smith's used "O" Rings that did not work very well or last very long.
