StatTrak™ Butterfly Knife | Case Hardened (Battle-Scarred)
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. It has been color case-hardened through the application of wood charcoal at high temperatures.

Description
The Butterfly Knife | Case Hardened is a classic CS:GO-era knife finish that carries forward into CS2 as part of legacy cosmetic models. Introduced through the long-running Case Hardened collection tradition, it quickly became known for its distinctive “worn stone” look—where each knife reveals a different blend of blues, grays, and heat-like highlights. The legacy CS:GO (legacy) model makes this skin especially popular among players who value traditional knife finishes.
As a Covert rarity item, this skin is considered highly desirable within the CS2 knife market. While exact drop rates can vary by container and game updates, Covert items are generally among the rarer pulls you can receive from weapon cases, meaning they tend to be far less common than Mil-Spec or Restricted tiers. This rarity is one of the main reasons the Butterfly Knife | Case Hardened remains a “must-have” for collectors and high-rank players.
You can find the Butterfly Knife | Case Hardened in all standard wear states: Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred—with the float range listed as 0–1 across these versions. StatTrak is available (Yes), letting owners display a counter for kills, while Souvenir is not available. Because Case Hardened finishes are highly pattern-dependent, even knives with similar wear can appear noticeably different.
Visually, this skin uses the Case Hardened finish style with Paint index: 44. The final appearance is driven by the pattern layout—typically showing a mix of icy blues and smoky dark tones across the blade and handle. For many players, the appeal isn’t only the color contrast, but also the way the pattern reads at different angles, making each knife feel unique in motion.
To obtain it, players look for the skin in Operation Breakout Weapon Case. It is not listed as being found in any named collections (none), and there are no souvenir variants—so the primary path is through that specific case pull. This makes it a frequent target for opening enthusiasts and a consistent presence in community discussions whenever new case strategies or collection rundowns come up.
In the wider CS community, the Butterfly Knife platform combined with the Case Hardened finish is often viewed as a standout classic—balancing recognizability, high demand, and visual uniqueness. Whether you’re aiming for a clean Factory New display or prefer deeper, more weathered tones in Well-Worn and Battle-Scarred, this skin remains a strong choice for players who want both prestige and individuality.
