Narrated by Council Tool president John Council, this video reveals a few key details (ribs inside the axe head to grip the handle); "just like it ought to be".
Have mentioned them before; Council Tool provide axe heads to Best Made and I believe also for newish marque in Montana called Meriweather Field Gear, who specialise in maple/walnut laminates for the helves. They use a similar process to produce eye-watering canoe paddles, w/ carbon faces for kayak paddles; as WhiskeyJack Paddles). Pretty stunning.
