My .02 cents: A knife is a tool. Tools sometimes break. But if I am honest here, I feel that only 4x in my lifetime of 57 yrs & working on vehicles since I was about 10 yrs old, & being a knife guy since about 40 ,did a tool break that honestly was not my fault. I attributed all to bad heat treat. You learn & move forward. I have broken 3 bayonets & a Gerber Mk 2 survival while in the Army & a Torx socket a few years back. In the end, all were replaced at no cost to me.
Moral of the story is: if you break a knife doing something that you consider normal , you need a different tool. I baton the living snot out of mine & have not broken a BK&T yet. But I do not throw them. I recently found my throwing knife I bought when I was 14 ! Lol
It's a bummer it broke on you though. No doubt. If I ever did break a BK&T blade, I would not hesitate to buy another. I think that they are a quality product that is still made in the USA at a working persons wages. That is no easy feat anymore these days.
