Not the original commenter but the knuckles are insanely OP. Especially when you get a book that "melee power attacks greatly increase your knockdown chance" and the "every melee fist punch (leather, iron, steel knuckles) heal you one health per punch" stuff gets insanely op. Just charge into a horde and focus one enemy at a time. Pair it with sexual rex, heavy armor, and the perk book "your armor does not weigh you down while In combat" you essentially become a tank. Infinite stamina, infinite knockdown, infinite attacks. It's deadly, which it has to be for melee.
As for HF, it's insanely OP. I always grab it the moment i can, I do believe what you engineered is a bug because I've never had that issue before. So i do wish you luck, i play on survivalist and the above build has never let me down!
May the hordes be small and the loot be large!
I wouldn't call it OP, but yes, with the books, heavy armor, HF, IS, you do become a tank and very very hard to kill.
HOWEVER, charging into a mob and punchy punching away, while fun, t'ain't so fun when "your exhausted" (need a vitamin) or, sprained arm. etc.
(it happens, annoying too)
I do the STR/FORT build a lot. Punch the individual/small groups, M60 for the big groups or the green ones.
One punch popping the head of a bear is soooooo satisfying though.

(same for one-shotting those stupid leaping lizard zeds. I really really hate them.)
I never noticed any extra food drain. But using food faster to heal faster, well, does make sense.
(and if you have a buncha points in Fort, then you should have a farm and be making better foods)
(sham should be going to sham chowder of course, as you do get an HP buff, which if melee fighting, you are going to want)
