its a different type of lock, the ones with cuts are pin tumbler, the cuts put the pins in the right place for the lock to open. That is a dimple lock, similar in that the dimples in the key set the pins to the right heights.

This is a dimple lock key, here's how they work.

Here in Switzerland, they are used everywhere. I dont even have other keys.
