Cockpit side window of Boeing 737

II hav a small query about Boeing 737, out of curiosity. Could not find a thread on 737, so posting here.

The query is regarding the side windows of the cockpit. Why, in a 737, the side windows have a V-dip on the bottom side? I identify a 737 from a 320 by looking for this V-dip.

And why is this V-dip so sharp? Sharp corners are stress raisers. It could been rounded, maintaining it's purpose.

There are many physical differences between the A320 and the 737. FYI cockpit fenestration is the same on the Boeing 707/727/737 series. I don't recall a cockpit side window failure in Boeing jet aircraft.

It makes the window easier to use as an emergency exit.

The straight bottom of the frame allows the window to run on the rail backwards. There is no worry about the integrity of the window itself- they are far stronger than the fuselage.
