Then we have the issue. . what is sharp ?
If it shaves hair off YOUR arm is that sharp ? What if it won't shave hair off MY arm ? My arm hair may be more wirey than yours, or whatever.
Pretty subjective thing.
You are not gonna get a three blade head to be as sharp as the proverbial razor. That just won't happen, but you should be able to get them sharp. Even sharp enough to cut your hair.
I think that one factor that is not seen while viewing the videos is the need to be VERY gentle with the strokes on the file and on the stone. You do not need to press hard at all once you have achieved the right grind. I personally believe more folks screw it up by pressing too hard than for any other reason. How do you see that in a video ?
Keep trying Caleb. Once you do it right, it all falls into place.

i hear ya, chuck. let's discuss ....
twin blade sharpening by file or stone requires some acquired skill to set and keep the proper edge angle. using a 'v' steel or carbide does not. no real skills needed with a KME sharpening system, either.
three blade heads have a larger angle to the blades since they're sharpened 2 at a time as they lay on file or stone. there is no blade angle to be concerned about. initial sharpening REQUIRES pressure of the blade to the file. honing demands little or no blade pressure.
there are steel and carbides that are meant for three blade heads - just a few whisks on each blade and it's sharp enuf to effectively kill game.
sharpness is not subjective. a blade will either shave arm hair or not. shaving hair is not the final blade intent - severing critter arteries is where it's at. you'll know when a blade is ready to sever hide, flesh and arteries.
there's another broadhead factor to consider - the point. imho, woodsman points shouldn't be left needle pointed, they should be filed to a angled pyramid point for better puncturing and bone deflection.
the point of all this (pun intended) is that a hunter needs to depend on the sharpness of his/her blades: broadhead, knife, axe, etc. bows and arrows are just the delivery tools for what matters most: a deep penetrating broadhead into the vitals of a critter.
