Is the Operation Breakout Weapon Case worth opening?

On average, no. Opening the Operation Breakout Weapon Case costs $9.77 (case plus key) and returns an expected $3.87 in skin value — you recover about 40% of what you spend, with the 0.26% knife/gloves chance (averaging $675.55 across the priced gold pool) already included. That percentage is not exact: 1 of this case's 13 knife/glove finishes is a plain, un-finished knife we hold no price for, and assuming a different value for it moves the answer to between 38% and 43%. Opening is entertainment; if you want a specific skin, buying it directly is almost always cheaper.

Expected Return per Opening

$3.87

Against a $9.77 cost (case $7.28 + key $2.49) — you recover 40%, though that figure rests on an assumption about this case’s unpriced knives — on the range of assumptions our data allows it sits between 38% and 43%

Expected Loss per Opening

79.92% of openings return a low-value Mil-Spec — the distribution, not bad luck, drives the result

Rare Special (Knife/Gloves) Value

$675.55

Average across the 12 of 13 finishes in this case’s gold pool we hold a price for, hit 0.26% of the time

Method: within a rarity tier every skin drops with equal probability, and within the gold tier every knife or glove finish the case can actually drop does; each outcome is valued at its cheapest listed wear across markets, with StatTrak folded into non-gold drops at the published ~10%. Because every outcome is taken at its cheapest wear and those are buyer prices rather than what a seller banks after market fees, the figure is rough in both directions at once. Prices updated Aug 27, 2026. The same numbers, computed the same way but published only where every outcome carries a real price, are on our case RTP breakdown. If you want a specific skin, trade-ups or buying it directly are almost always cheaper than opening for it.

What this figure assumes. 1 of the 13 knife/glove finishes this case can drop — ★ Butterfly Knife — are plain, un-finished knives we hold no price for. They are assumed to be worth $675.55, the average of the 12 finishes we can price. That assumption is not a floor: if those knives are worth less the real recovery is nearer 38%, and if they are worth as much as this pool's dearest finish it is nearer 43%.
