Uniknot works fine on braid and two uniknots are perfect for joining braid to mono. I use 6# yellow Suffix tied directly to lures for panfish and crappie .
CrappiePappy is 100% correct on the children's Fiscars scissors. They work perfect for braid and mono. $1 apiece at Walmart. I keep several on hand in various boxes.
I honestly don't know where all these legends about braid came from. Cheap kid's scissors cut it clean and quick and I've caught bream, bass, crappie, stripers and catfish using just the braid tied directly to the hook or lure.
