nobody’s broken a unicrown one, not even the fatigue testing machine
the actual root cause of the failures is that this blade is a piece of shit that was designed wrong: http://www.cycle-frames.com/bicycle-frame-tubing/NOVA-CRMO-ROAD-OVAL-0.9-0.6-NOV_CXFB_OVL_0.9.html
it’s not possible to build a safe disc fork with it, and the wide 28.6 biplane crown can’t use normal fork blades
