I think i have figured out a way to do it but i want some verification.
Would the ability to apply sneak attack as a swift action as per the combat feat "strangler" work with the attack action afforded by the combat feat "hamatula strike"?

Basically, i want to know if i figured out a way to apply sneak attack while grappled at reach range.
