Worksharp, DMT Aligner or something else?

I'm wondering what would be best or what you guys think would be best for sharpening pocket knives anywhere from 6" inches in blade length and less. Also what would be best to sharpen karambits and hawkbill blades? Finally how do you guys sharpen your serrations and I just bought a fairly cheap 20 dollar machete from my friend and would like to know a somewhat easy way to sharpen that. Thanks for all your help

Machete, mill file/ bastard file.

I know there is a recent discussion on what quality files there are out there but I don't recall the brands mentioned.

With the use I've had, Nicholson files are good.
