Knife and glove Trade Ups are the highest-stakes contracts in CS2. This is a separate special contract from the standard one: it takes 5 Covert (red) skins instead of 10, and it returns a knife or a pair of gloves rather than a skin of the next rarity up.

The possible outcomes come from the collections your 5 inputs belong to. Each contributing collection adds its knife and glove pool to the outcome set, and the chance of landing in a given pool is the share of inputs that came from that collection. The wear you get is derived the same way as in a standard contract: each input float is normalized inside its own skin's float range, those values are averaged, and the average is scaled into the float range of whichever outcome you hit. For inputs with a full 0 to 1 range the normalized and raw floats are the same number. Either way, low-float inputs are the only lever you have over the condition of the result.

Most of these contracts lose money on average. A knife or glove pool holds many outcomes of widely differing value, while 5 Coverts are expensive to buy, so the average outcome is usually worth less than the inputs cost. The contracts listed below are the ones where current market prices make that not true, which is a small and constantly changing set. Treat every expected value here as an estimate from the last hourly price refresh, not a guarantee.
