Made Some Firewood Today
RyanY:
Bizarre. Looks like a tension break which is unlikely in hickory. So maybe due to grain but how dry was it? Looks like it started at the right side that’s away from the knot.
Jim Davis:
Agree with Ryan. Doesn't look like the way hickory would break. I have hickory bows with nasty grain run-out that have held together just fine. Something out of the ordinary here.
Hamish:
Hickory is more forgiving than most woods in tension. That being said its like all wood, given a flaw or more stress than the design can take it will eventually break.
I no longer use hickory with even a tiny pin knot in it for backings, unless it will end up in a non bending handle section.
I mainly make backed narrow elb less than an inch wide.

Absolutely. Even the mythical tension properties of hickory have their limits ;)
I also agree that it doesn't look like a 'normal' hickory break. On a properly looked after self stave I wouldn't have worried about that knot.
BowEd:
Small pin knots like that have never amounted into a breakage on any of my hickory bows.
Any wood can get too dry.
I've seen post holes in hickory that will break them though.
