I am looking into getting a double bit axe, but I am wanting one with different beveled angles so I can use 1 axe for both chopping and splitting. (Think Nessmuk style) I have a couple photos of a bit that's for sale, but I can't tell if it has two different edges or just 2 of the same.

I can't figure out how to add pics but enter this into Ebay to see what I mean.

I am in no means an expert, I know just enough to be dangerous. Lol

Which is not difficult, but if you’ve never done it before you might not get the geometry exactly right the first time.

Not a problem though, just keep improving it little by little til you get to perfect.

Then stop.

ETA: just checked my closest two, a TT Kelly perfect and a Craftsman, with a dial caliper. Both asymmetrical. They’re old though, so who knows how they were originally.

I have seen a Collins that that one bit was forged thicker than the other.
 
I was under the impression that the cheeks would have to be pushed out more on the one side to help aid in the splitting of the log.

If it is just the edge bevel being different on either side then wouldn't that be similar to trying to split with just a dull axe?

It's not typically a splitting bit vs a cutting bit.
Usually it's your fine sharper edge you take more care of, and one less sharp more durable edge that you use for cutting around the ground and through the bark which could have rocks and other debris in it.
 
No, a dull axe would present a rounded edge to the end grain which would crush the impacted wood fibers. A blunt geometry with a sharp edge would part the fibers initially, then immediately start wedging them apart to produce a split. This assumes you’re splitting from the end.

I believe more users use a two grind axe as a “clean-dirty” combination than “chop/split”. There are more effective splitting approaches than using a double bit axe.

If you need to split a lot, I predict you’ll switch tools before long.
