Because it was hit harder I would assume. Kydex gets very brittle when cold (impact toughness is less than 1/10 of room temperature at sub-zero), however it still obviously has some impact resistance.
The type and nature of the impacts are also of consequence, hitting it with a piece of wood is different than steel, and hitting a sheath that is free to move is different than hitting a sheath which is immobile.
To clarify, the above posts are not a line of arguement towards "kydex sucks", it does quite well for some things, mainly its high strength allows very slim sheaths with a secure shape lock.
It also holds well against abrastion, cuts and is basically immune to rotting.
However it also has a much lower temperature resistance than some of the other sheath materials, it is highly biased to critize leather for its obvious weakpoints (like rotting in extremes) but to pretent the same problems don't exist in other conditions with Kydex.
Chas has outlined other problems with Kydex in a recent thread on rec.knives, such as problems with constant heat shocks.
