Knife Master + Arcane Trickster, knife sneak attack dice?

[VerdantSF]

How is the extra sneak attack damage from Arcane Trickster factored in for Knife Master Rogues? KM d8s + AT d6s or is all d8s when using knives/daggers specifically?

As long as you use Daggers or the types of daggers stated in the Knife Master's description, all sneak attack damage is D8's.
