Recently I re-handled my broadaxe from a piece of wood handed off to me - mistake No. 1. In the end what I got was useless because these angles were off or maybe just not suited to my way of work. You see how the line of this grip is more or less parallel to the edge, when what is needed (yellow indication) is the handle that opens up the angle between edge and grip by 5 or 6 °.
On the other hand the off-set came out pretty much how I like it, which is to say, a minimal of curving and just the right point of articulation at the knuckle.
Of course this is an axe of a different order than that Richard and his Canadian colleagues were using.
