Sure, np.
This is from FairwheelBikes (a lot of people here cite this place as being reputable):

This is the issue I had with my dropout (this is a common issue with older dropouts; notice the recommendations to fix the problem?):

My Old Steel bike has horizontal dropouts:

It's VERY difficult to get the KCNC skewers let alone a regular external cam skewer tight enough for the rear axle not to slip on horizontal dropouts, hence the internal cam skewer. Remember, when these steel bikes were made, everyone used internal cam skewers (you can read about Campagnolo and what his first successful product was if you want).
Again, I own the KCNC skewers, I like them, but it's pretty obvious that their function is predominantly their light weight and not their clamping power.
