I was making a list of 6 volt damper diodes and came across 6DK3 a manly tube that can pull 400ma load, but it has a grid. Why would this be?

According to the datasheet you linked to it doesn't, it has a heater insulation coil. I haven't a clue how that works.
It appears to be around the heater. It’s not a grid as it’s not between Cathode and Plate.
Hopefully somebody who is familiar with this can shed some light on how this works, I’ve never used a tube with such.

Yeah after I posted post I saw it wasn't actually a grid but just looked like a grid. Maybe they coated a wire with insulation and wrapped it around the filament to prevent any chance of a short to the cathode? I see too the cathode is brought to the top cap, so tying one leg of the filament to the cathode might be a problem to build? Clueless.

For the use as damper diode and the heater common with the other tubes there is a very high voltage on the cathode.That "grid" is to keep enough distance between heater and cathode.
You can connect it evt to the B+ for a better voltage distribution.
For an audio supply connect to the heater if separate heater or to ground with a common heater supply.
