★ Butterfly Knife | Rust Coat (Well-Worn)

CS2 Covert Knives Discontinued

★ Butterfly Knife | Rust Coat (Well-Worn) — This is a custom-designed balisong, commonly known as a butterfly knife. The defining characteristic of this weapon is the fan-like opening of a freely pivoting blade, allowing rapid deployment or concealment. As a result, butterfly knives are outlawed in many countries. This memento from Siege is still perfectly operational although the exterior surfaces have rusted.\n\nScars build character

Right now it goes for $580 to $981 across 6 marketplaces — a 69.2% spread. Liquidity is low: just 1 sales a day. An item like this can sit for weeks, and an attractive listing price does not mean anyone will pay it.

We track 2 wear levels of this skin. The cheapest is BS at $536, the priciest is WW at $580 — a 1.1x difference for the very same artwork, the wear is all that changes. Over the past 30 days the price stayed between $529 and $1 150, and it is now 4% higher than a month ago. The all-time high is $1 150, the low is $529. Float for this skin runs from 0.4 to 1.0 (the range of the whole skin, not of a single wear): the lower the number, the cleaner the finish, and copies at the edge of the range are valued separately.

This skin does not exist in every wear: you can find Well-Worn, Battle-Scarred, while Factory New, Minimal Wear, Field-Tested never existed — its float range only starts at 0.4. The cleanest copy obtainable at all is Well-Worn.

Marketplace prices

ⓘ

★ Butterfly Knife | Rust Coat (Well-Worn) is listed on 5 marketplaces. The most you keep is on steam: $981 minus a 15.0% fee leaves $853 net. The least you keep is on lis: $580 minus a ~9.7% fee leaves $524. The $330 gap comes from both different listing prices and different fees; a large gap usually means the listings differ in wear or condition, so check the item itself before selling. If you need cash out rather than Steam wallet funds, the best option is marketcsgo, $566 net.

Fees are the marketplaces' standard seller rates; Steam's 15% is charged on the seller's amount, so the net is the price divided by 1.15. Volume discounts, promo codes and regional specifics are not included, and Steam proceeds stay in the Steam wallet.

A rate marked with a tilde (~) is our own estimate, not a published figure: it is derived by comparing the marketplace's own buy and sell prices. The real cut varies from item to item and is usually worse on cheap listings.
