# CS2 Knife Index — IDX-KNIFE perpetual

> CS2 index · Basket of 12 Factory New knives. One unit = one each of 12 liquid Factory New knives, from Karambit and Butterfly Fades down to Gut and Paracord knives, so the index tracks the whole knife tier. Built to hedge tier-wide shocks such as Valve's October 2025 trade-up change that let Covert skins trade up into knives and knocked knife prices down across the board.
