$4 torch score!

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.

You can buy aftermarket flashback arrestors. I think the new torches have them built in somehow. But, you are probably right, they are designed to protect your hoses, regulators, and tanks, not the torch body.

I have flashback arresters on my regs. I just brought home a few more chainsaws that will be taking my attention for a bit, but I hope to get the torch rebuilt before long.
