That one appears to be double beveled. You'd have to re-grind a typical broad hatchet to get that edge. Single bevel and double bevel each have their own advantages for carving work. If you're interested in a double beveled work hatchet then check out a riggers hatchet, shingling hatchet or claw hatchet.
Also, if you plan to use the poll more than occasionally then I'd suggest putting a straight haft on it. But if you're mostly using the bit than go with the curved haft.
