I bought a made in China Marbles Double Bit this summer.
Its actually a good little axe for the money (20-30$).
The profiles are thick but It actually chops pretty good, a whole lot better than i though it would.
I haven't had any problems and would use it for camping but i have talked to 2 or three people here who have had the heads come loose on theirs after some limited chopping.
So when i bought mine i expected i would
have to re-handle it but luckily i've had no problem with it so far.
I am going to refinish mine and make sure the wood in the eye is well soaked in tung oil to make the fit extra tight.
I also bought a U.S made Vaughan sounding-axe/sub-zero around the same time and sadly the fit and finish on that was inferior to the Chinese Marbles.

The Vaughan handle was skewed off to the right about 10 degrees or so and i had to do some major file work to make it sharp enough to use.
I expected to have to file it but the skewed handle was a bit of a surprise.
However i managed to mostly correct the handle problems by a fair amount of reshaping. It works now but its flatter because of the reshaping.
Post-modifications I rather like the Vaughan, its so small you can carry in a cargo pants pocket. 11 inches long and only 10 ounces total weight.
(I still may re-handle it sometime though.)
And of course its still not a double bit , lol!
The best new single-bit axe i've bought in recent years is the U.S made Snow and Nealley Penobscot bay Kindling axe from 3Rivers Archery (only 35$).
Its the best made axe i've seen in many years, perfect fit and finish, straight grain, ready to go out-of-the-box!
I love my Wetterlings but the Snow & Nealley has them beat on on fit and finish.
S&N make a full sized double bit but unfortunately they don't make one as small as the Fort Meigs.
