Why are keyed drill chucks still available for modern tools?
Keyed chucks still get a better grip on any bit. I'm willing to use keyless on my portable drill -- though mine will take a key too, and there are times when I use it. I wouldn't trust keyless on a ...

Why are keyed drill chucks still available for modern tools?
As @keshlam pointed out. My drill presses both have keyed chucks and it allows much greater torque to put a stronger clamp on the bit.

Cutting a stack of paper into a shape with a router
Is this a workable approach?
I don't think so. I think a spinning bit is going to give you a fairly rough edge, and it also won't get into the inside corners that your shape has.
Is it safe, or am I ...
