Anyone here got any idea as to why this may have happened?

Probably cos more than a few have seen it, or what happens when a blade fails and goes up/through the discharge shoot:wtf:

 

Not a blade but the flywheel but, looking at the pics still scares me..

Tip, If you want to check your knifes before fitting for cracks, spray with brake n clutch cleaner, as the fluid evaporates any cracks will be the last to evaporate and soon become apparent as the fluid will seep into any hairline, this will also clean your knifes ready for fitting.
