Melee weapons (Fallout 4)

Greetings to members of the forum!
A question arose about melee weapons, to which I could not find an answer in any way, since I was playing a melee officer.
There are boxing gloves and brass knuckles in the game - are they melee weapons or fists?
Those. I want to know which perk to pump in order to raise the damage with the Furious Power Knuckle Dusters, which falls from the Swan.
In theory, you need to pump in the "Major League", which raises the damage to melee weapons. But! In all the guides that I found on the net, they say about this brass knuckles that you need to pump in the "Iron Fist" for it.
