SHORT ANSWER

Can you trade up to a knife in CS2?

No — standard CS2 trade-up contracts cannot output a knife or gloves. Trade-ups take 10 weapon skins of the same rarity and return one skin of the next rarity up, and the ladder ends at Covert. Knives and gloves sit in the separate ★ (Extraordinary) tier and only drop from cases opened with a key. So a "knife trade-up calculator" really means two things: a trade-up calculator for high-value skin contracts, and a case ROI tool for the odds of unboxing a knife.

How CS2 trade-up contracts actually work

10 inputs, same rarity: every contract uses exactly 10 normal (or 10 StatTrak) skins of one rarity from the same trade-up pool.
One tier up: the output is a single skin of the next rarity, picked from the collections of your inputs — Mil-Spec → Restricted → Classified → Covert.
Covert is the ceiling: there is no rarity above Covert in a trade-up, so 10 Coverts cannot become a knife. Knives/gloves are not in the trade-up pool at all.
Float carries over: the average input float is normalized through each output skin range, so it changes the output wear, not the rarity.

Knife trade-up FAQ

Is there a 10 Covert to knife trade-up?

No. Trading up 10 Covert skins is not possible because Covert is the highest trade-up rarity — there is no knife output tier. This is a common misconception.

What about the "5 Covert" or special contracts?

CS2 trade-ups always use 10 inputs of one rarity. There is no official contract that turns weapon skins into a knife or glove.

What are the odds of getting a knife from a case?

A rare special item (knife or gloves) is roughly 0.26% per case opening. Use the case ROI tool to compare expected value before opening.

So what should I use the trade-up calculator for?

For weapon-skin contracts: pick 10 same-rarity inputs, set the float, and see the output odds, floats and expected value before you buy inputs.
