Extra Knives is a prefix that turns up on Main Hand, but only on gear tagged knife_toss. It gives kitKnives: +1 to +1 at its lowest step, +2 to +2 at its best — and you need item level 116 before the best one can appear at all.
It comes up at weight 5 when the game rolls affixes, never doubles up with another affix that does the same job (kitKnives), and it is what puts Twinned, Bristling, Manifold, Brimming and Countless in an item's name — so you might pick up a Twinned Wand.
No Unique carries it at a fixed number.
