Yep, black locust. You have to be careful with it because it frets easily from tillering issues and over-stressing (I've yet to quantify what over-stressing is on "average" locust) but simply put its higher modulus of elasticity/stiffness means less wood and mass is required for the same resistance. Tempering the belly makes the wood quite set resistant even in those narrow profiles.
Locust also works from the bitter cold of winter and blistering heat of summer in the Nevada desert to the muggy rainforest of Washington's summer. People can say no wood besides osage does this but the fact is locust has and does
The two flaws are the need for heat treatment and its lower jenka hardness, meaning the wood will dent easier than osage or hickory. Toast the belly and don't use it as a sword and you're set
I haven't used honey locust but its numbers and reputation put it pretty well into the middle tier of woods where I think locust is right up at the top with yew and osage.
