Earlier quoted context omitted.
I was in youth league hockey as carbon fiber sticks went from unheard of to ubiquitous. Carbon sticks failed in a spectacular way, but wood stills would also fail. They wouldn't break in two during a slapshot, but they would generally split along the bottom of the blade. If refs noticed it, you could get a penalty. By the time my parents caved in and bought a wood stick, I was at the point of consuming one new stick…
If refs noticed it, you could get a penalty. I'm curious, what penalty gets called here? I wasn't aware there was a "your equipment fell apart" penalty.
I played in Canada, but this ruling seems quite similar to what was in effect for us: https://www.usahockeyrulebook.com/page/show/1084649-rule-605...
I think the worry is a broken stick has a chance of producing something sharp that can injure others. I think it is more of a worry when the break is along the shaft of a wooden stick (as you could stab someone, you're basically wielding a spear) but even a split along the bottom of a wooden stick's blade has the potential to lose splinters.
