Hiya, longtime lurker here, first post. Aware that it’s a minority position here, I’ve hafted many hammers during my career in the construction trades and found it useful to leave a “shoulder” beneath the head. I’ve replaced broken handles (with no shoulder) with shouldered ones and they’ve seemed to last longer, in the hands of the same careless gorillas who bend their pry bars and break off sill bolts. I also haft (some of my) hatchets that way, especially when carving my own handles, although not my 36” falling and splitting axes which take repeated full strength two handed slams.
That said, i think I’m also in the minority of how I hang. Among other things, I radius the edges of the eye opening, I make a fitted wedge from the same species as the handle (preferably the same billet), and I often use 2 angled wedges to bring tension fore and aft on the eye, as well as the sides. No steel wedges, in fact I have a collection of them removed from broken handles. And I always leave the tip/wedge sticking proud of the eye, sometimes by 1/2”.
So HH, there’s a dissenting opinion for ya. Hope I can post this without throwing dirt on the other members who posted, cause I partially agree with what they said.
