Knafs is a colloquial, tongue-in-cheek way to say “knives.” It's also a goofy brand of knife-related products and ideas. Origin: when mispronounced, “knives” becomes “knifes.” With a Southern accent, “knifes” becomes “knafs.” Why Knafs? Shucks, son. The web domain was only $12.99 and we're cheap suckers!
