Any idea on what techniques were used to restore rust this bad on a very old axe head?
I'm very surprised the engraved details were recovered.

Fastest, cheapest way: Wire wheel on a benchtop grinder. It's kind of a pain in the ass and you can damage the piece if you aren't careful.
Safest, easiest way: Evaporust. Costs quite a bit though. HF carries it. Get a 20% off coupon for someone and buy it.
Fairly easy, fairly cheap, most awesome way: electrolysis. Moderately difficult to setup but works great and won't damage the piece. Watch out for off-gassing and don't smoke around it.
Other things also work. Molasses, citric acid, etc. They can eat into the metal if you aren't careful and have varying levels of effectiveness.
Electrolytic rust removal most likely.
theres no way thats the same axe head

That looks like electrolytic from the coloring.
Electrolytic works partially to remove rust and partially converting some of the red rust that's already there to Fe3O4, a different kind of rust, which is why it's so dark. Fe3O4 protects against further rusting very well, though it can be worn away. This makes it useful for a museum piece that won't see much use, and it's still nice for items that will as long as they're kept maintained.
It requires an large relatively expensive setup, and must be done outdoors due to fumes.

There's some others you're missing:
Absolute cheapest, albiet extremely slow way: dollar store wire brush held in a bench vise. Piece is rubbed across it by hand. Much slower but much more control and easier to stop with less accidents. Would not reccomend for appearance though.
Super cheap, but can be spotty: Vegetable oil soak. Less likely to cause fuckups than molasses and citric acid, but also will leave many areas still rusted.
On top of this you forgot that harbor freight is having a small sale later in may with a 25% off coupon.

damn thats a hot ax
Why has nobody mentioned just soaking it in coca cola and using a fucking sponge?
I cleaned the rust off an entire car with that shit.

You soaked your ENTIRE car in coca cola?

why has no one mentioned the vinegar method? apply baking soda to the pieces AFTER to neutralize the acid. all you do is put piece in vinegar bath and wait 2 days then the rust wash off, you MIGHT need to use small wire brush or steel wool to make it perfect using this method.

after cleaning, cook it in parafine oil. wipe off excess. that will conserve it.
be careful

Cant I just soak the thing in CLR?

Acid bath is the best solution (cola and vinegar are both weak acids).
I use the vinegar for BMX restoration.
Its non toxic and works well.
DO NOT leave overnight.
Check it every hour or two.
Use a sponge that has the scotch brite pad on one side (use blue or pink, not green).
Wipe down and repeat.
Electrolysis is the only legitimate way to de-rust steel. Anything else will damage the base metal, either by abrasion or by etching. Electrolysis will only remove the rust, no matter how long you let it run for. It also produces no waste (keep the bath in a bucket, ready to use) and the ingredients cost pennies.

Ffs soak the damn thing in distilled vinegar, wipe it off after a few hours and change the vinegar. Almost spotless in about a day

The engraving is actually inlay. And its silver. If you wire wheeled this you would probably rip out the silver..
