What are Case Hardened Skins?

Case Hardened skins are weapon skins with unique, multicolored patterns. The design is inspired by the color case hardening process, also known as surface hardening, which involves heating the surface of iron or steel with elements like carbon at high temperatures. In the traditional process, wood charcoal and a concentrated liquid are used to heat the metal, producing a hardened surface layer and the distinctive color case hardened appearance. This process results in a mix of blues, purples (which are also present in some patterns), and gold on the surface, creating a luxurious and expensive-looking visual pattern. While Case Hardened are some of the rarest CS2 skins, the real reason why they are so popular is the legendary Blue Gem patterns.

The blue gem pattern, featuring a high concentration of blue, is the rarest and most valuable among Case Hardened patterns. The amount of blue present on the surface determines the rarity and value of the skin, and typically, Blue Gems have a large blue area. These are rare Case Hardened variants whose pattern index (also called the seed, not to be confused with the float value) places a large blot of blue paint on the skin, which resembles a literal blue gem. To take a deeper look at the different forms and patterns, for example, the AK-47 | Case Hardened #661 is a famous Blue Gem skin. Blue Gem skins in CS2 can greatly differ in price, and while some cost less than one thousand dollars, the rarest Blue Gem skins can be worth over one million dollars! The rest of the patterns are less valuable, but even a little color variation can enhance the appearance and never hurt the skin’s appeal.

Why are Case Hardened Skins so expensive?

If you’ve been browsing trade offers for some of the Case Hardened skins on the market, you’ve probably already noticed that they often carry high price tags. Case Hardened knives and the AK-47 usually cost hundreds of dollars or more even with an ordinary pattern, while the Five-SeveN version is far cheaper.

One of the most important aspects of their price is the CS2 rarity. Case Hardened skins range from Restricted (Five-SeveN) and Classified (AK-47) up to Covert knives and gloves. The knives are the rarest in the entire family, which elevates their price tags even further.

In addition, some of the Case Hardened pattern index versions can be worth even more, and are often hunted by big-time collectors, looking to improve their CS2 inventory. Because of this, these rare Case Hardened patterns are constantly a hot commodity, only driving their prices even further.

What are the best Case Hardened skins?

If we’ve captured your attention, here is a list of the best Case Hardened skins you can get in CS2:

1. AK-47 | Case Hardened

The AK-47 Case Hardened is the crown jewel of Case Hardened skins. Introduced in the Arms Deal Collection back in 2013, with the very first CS:GO weapon case, Case Hardened is one of the best AK-47 skins available in the game. Renowned as a reliable assault rifle used by players around the world, the AK-47 | Case Hardened can be obtained by opening the CS:GO Weapon Case. In 2024, a StatTrak Factory New blue gem AK-47 with pattern #661 reportedly sold for over one million dollars, making it one of the most expensive CS2 skins in the history of the game. In addition to blue gems, collectors also hunt other rare patterns, such as gold-heavy “gold gems”, and inspect each skin to see how much blue (or gold) shows on the visible side. In gameplay, the AK-47 is most effective when fired in controlled bursts for maximum damage.

How to get Case Hardened skins?

If you want to get your hands on Case Hardened skins, there are three ways to do that, just like with other weapon skins in CS2. You can open CS weapon cases, use the Steam Community Market, or trade skins at a third-party trading market.

While opening CS weapon cases to get Case Hardened skins might seem like an attractive method, you have to keep in mind that with the CS case odds your chances of opening a single Case Hardened item are extremely low, and this goes double if you’re aiming for a specific Case Hardened pattern index. While you only need a weapon case together with the CS2 case key, opening a single Case Hardened skin can eventually cost more than simply buying the skin.

Because of this, it might seem attractive to buy Case Hardened skins at the Steam community market, but keep in mind, that this isn’t the best idea. Although the integrated Steam trading features are easy to use, Valve takes a cut (15% in total fees) out of every transaction made on the market, effectively shifting the costs onto buyers. While it might not seem like much, with high prices of Case Hardened skins this small cut can come up to quite a lot of money.

If you want to get Case Hardened skins, the best way to do this is to trade CS2 skins on a dedicated third-party market, like SkinsMonkey. With an instant bot-trading feature at SkinsMonkey, you can trade skins instantly at any time, and you’re always bound to get the best deals possible. In addition, you can also use various different payment methods, like crypto.
