Classic Knife Case Hardened Blue Gem Patterns

If you want to discover what are the classic knife case hardened blue gem patterns because you want to know how much your skin is worth or because you want to buy an authentic Blue Gem, this article will bring you all the information you need.

We will explain the different tiers of patterns for the classic knife blue gem, bring you examples on how the prices change depending on the pattern, how to identify an authentic Classic Knife Blue Gem and let you know why it’s one of the most sought after skins nowadays.

About the Case Hardened Finish

Before we dive into what makes a Classic Knife Case Hardened a blue gem, we need to start by talking about the Case Hardened finish. 

Basically, it’s a pattern of different colors including blue, dull gold, gray and purple, which is then transferred to the skin, in this case, the Classic Knife. It is created by case hardening the metal surface of the knife, which is done in an aleatory configuration.

It was first introduced in 2013 when Valve launched the  Arms Deal Collection, which included an AK-47 with the Case Hardened Finish, and since then, the skins with this finish have become extremely popular, especially knives such as the Classic Knife.

There are 1,000 possible combinations with varying degrees of blue, purple, dull gold and gray. However, only the patterns with a greater content of blue can be labeled as blue gem, hence only 149 patterns belong to this category, and they are further divided into four different tiers: Tier 1, Tier 2, Tier 3 and Tier 4.

Therefore, a Classic Knife Case Hardened with the blue gem label will sell for more than a standard Classic Knife Case Hardened, and it’s all due to the percentage of blue present on the blade. 

Now that it’s clear what the Case Hardened finish is and its link to the “blue gem quality”, let’s check the 149 patterns of Classic Knife Case Hardened blue gems.

Full List of Patterns for the Classic Knife Case Hardened: Blue Gem & More

Here you have the full list of patterns for the classic knife case hardened skin, properly categorized in tiers from 1 to 4:

Tier 1

Here you have the full list of Tier 1 patterns for the Classic Knife Case Hardened, which are known as the real blue gems:

• 169
• 456
• 601
• 316
• 577
• 403
• 58
• 681

They are the real classic knife case hardened blue gems because they have the highest amount of blue hue from the Case Hardened color sheet, which is highly sought after. From this tier, the pattern 403 is the priciest and most demanded blue gem, because the blue hue covers 98% of the blade.

Therefore, if you got a classic knife with any of the Tier 1 patterns, you can consider yourself lucky, because you can sell it for a premium on the Steam Community Marketplace, or at third party skins trading sites.

You will notice that the lower tiers will include plenty of more patterns than the Tier 1 and Tier 2, which further proves how valuable the blue gem skins are, because they are more scarce and hence harder to obtain.

Tier 2

Here you have the full list of Tier 2 patterns for the Classic Knife Case Hardened skin, which have plenty of blue hue on the blade:

• 704
• 449
• 281
• 585
• 922
• 634
• 55
• 210
• 351

Even though they are not as valuable or rare as the Tier 1 patterns, such as the authentic blue gem 403, a classic knife Case Hardened with a Tier 2 pattern such as the 704 will sell for a premium too, as they have plenty of the blue hue on the blade.

Tier 3

Here you have the full list of Tier 3 patterns for this skin:

837, 915, 880, 556, 628, 345, 850, 202, 583, 288, 668, 239, 447, 372, 67, 170, 336, 417, 349, 632, 496, 533, 107, 529, 887, 262, 503, 393, 162, 430, 269, 954, 383, 166, 797, 867, 180, 374, 157, 588, 537, 116, 916, 624, 715, 103, 187

The Tier 3 patterns have less blue hue when compared to the Tier 1 and Tier 2, but they still got enough blue for traders and players to be interested in buying them. Even though you can cannot sell them for as high as premium patterns such as the 403 or 704, you can still take advantage of overprice.

Tier 4

Here is the full list of Tier 4 patterns for this skin:

959, 523, 176, 812, 669, 88, 507, 525, 286, 429, 700, 179, 698, 442, 899, 222, 91, 818, 941, 613, 866, 675, 606, 108, 325, 750, 610, 828, 955, 519, 294, 516, 235, 794, 821, 227, 619, 151, 693, 710, 299, 600, 807, 387, 59, 869, 95, 719, 292, 400, 805, 203, 689, 995, 665, 14, 973, 298, 526, 547, 462, 84, 504, 551, 124, 859, 878, 646, 138, 806, 564, 680, 315, 872, 3, 528, 902, 790, 820, 546, 969, 740, 651, 212, 910

This tier of patterns for the Classic Knife Case Hardened have minimal blue hue over the blade, making them the closest to the market price for this skin, although you can always charge a small premium. However, the price is noticeably cheaper than an authentic blue gem from Tier 1.

Therefore, if you have one of these, you can guide yourself by the prices on the Steam Marketplace or third-party trading sites to see for how much you can sell your skin with one of the Tier 4 patterns.

Understanding the Different Tiers of Patterns for the Classic Knife Case Hardened Skin

The patterns for the Classic Knife Case Hardened, just like for every other skin, range from 1 to 1,000, bringing the weapon a different aspect one from another. From all the possible 1,000 combinations, only 149 patterns belong to the category of “Blue Gem”, because they have a significant prevalence of the blue hue on the blade.

Therefore, it means 851 patterns for the Classic Knife Case Hardened skin do not belong to this category, because their blades lack the necessary amount of blue hue to be significant. 

From all the 149 patterns that are considered blue gems, as we have seen, they are divided in tiers, depending on how much blue hue they have. Logically, the Tier 1 patterns have the most blue hue, often covering from 90 to 98% of the blade, making them the most sought after Classic Knife Case Hardened skins, and hence the most expensive.

To put this into context, we will analyze the percentage of blue hue of different patterns from the four tiers, so you can fully understand it:

As you can see, the percentage decreases in the lower tiers, and hence we can conclude the following:

• Tier 1 patterns contain 90% to 99% of blue hue

• Tier 2 patterns contain 80% to 90% of blue hue

• Tier 3 patterns contain 70% to 80% of blue hue
• Tier 4 patterns contain from 50% to 70% of blue hue

Therefore, for a Classic Knife Case Hardened to be considered a blue gem, it must have at least 50% of blue hue on the blade, and the more, the better.

We also need to take into account that all Case Hardened patterns will have a presence of the following colors as well: purple, dull gold, and gray. Therefore, a Tier 1 pattern will have mostly blue, with minimal purple, dull gold or gray, whereas the colors of Tier 4 pattern will be more balanced.

Price Difference for the Different Classic Knife Case Hardened Blue Gem Patterns

The price difference between the tiers of the Classic Knife Case Hardened patterns can differ widely, and the following table shows it clearly, by comparing different patterns from each tier:

As you can see, the price difference between a Tier 1 pattern and a Tier 4 pattern is quite evident, and it all comes down to one single factor: the pattern with the most blue hue on the cover will be more expensive and demanded than patterns with minimal blue.

It’s worth noting that factors such as the wear of the skins, and if it’s StatTrak or not, will influence the price as well. For example, a StatTrak Classic Knife Case Hardened (Factory New) skin with a 403 pattern will sell for more than the same skin but with Minimal Wear. 

The table simply brings you an average, which clearly shows how the prices differ depending on the tier of the pattern. Because the closer it is to having a fully blue blade, the more valuable it will be.

It’s also worth noting that a Classic Knife Case Hardened with a Tier 1 pattern is hard to find even on third party trading sites with thousands of offers and plenty of traffic,  and the same goes for Tier 2 patterns.

This is why we have picked the available patterns from Steam and third party trading sites, such as the pattern 456, because other patterns such as the 403, are extremely hard to find if not impossible, unless you find a private deal. 

How to Get a Classic Knife Case Hardened Blue Gem

If you are here to learn more about this outstanding skin because you want to obtain it, we will let you know about the two available methods, so you can get your own blue gem.

Method 1: Open the CS20 Case

The only case that contains the Classic Knife is the CS20 Case, which contains this skin as a Rare Drop. Therefore, if you want to try your luck and see if you can land this skin, you can open this CS:GO case.

Nonetheless, before you do it, you need to consider the following facts:

• The Classic Knife is labeled as a Rare Drop, hence you only stand a chance of 1 in 391 to get it, giving you a probability lower than 1% to get this skin
• There is no guarantee you will get a Classic Knife with the Case Hardened finish, as it’s a random process that superimposes a square text over the knife to give its characteristic look, and hence there’s no way to control it
• There is no guarantee you will get a Case Hardened finish with a blue gem pattern, because only 149 patterns belong to this category, as they contain the highest percentage of blue present on the metal surface. Remember, there are 1,000 possible patterns for the Case Hardened skins
• The CS20 Case offers a ROI of barely 57.55%, which makes it a high risk case as you’re expected to just get the half of your original investment back after 100 tries

If you put this all together, your chances of getting a proper Classic Knife Case Hardened blue gem are extremely slim, even if you’d just be happy with a Tier 4 pattern. Now, if you’re aiming at a Tier 1 pattern, we can only wish you good luck. Because dropping a Classic Knife Case Hardened with the pattern 403, for example, which is an authentic blue gem with over 98% of blue present, is nearly impossible.

However, if you still want to give it a try, here you have more information about the CS20 Case, so you can try your luck and see if you can drop a Classic Knife Case Hardened blue gem:

• Case Price: $0.59
• Key Price: $2.50
• Total Price: $3.09
• ROI: 57.55%

Based on this, supposing you’re lucky to get a Rare Drop after 391 opens, and it happens to be a Classic Knife Case Hardened with a blue gem pattern, you’d have to spend $1,208.19 USD to get the skin.

Judging from the odds alone, it’s evident there’s a bit of risk involved. As we’ve mentioned before, there’s no certainty that the Rare Drop will yield a Classic Knife with the Case Hardened finish, let alone one with a blue gem pattern—much less if it’ll be a Tier 1 or Tier 2 pattern.

And it’s also important to note the ROI of 57.55% is just a general estimation. Let’s suppose you get the blue gem classic knife after 391 opens ($1,209.19 spent), but it happens to be a pattern 606 (Tier 4). In this case, you can sell it for $250 to $300, bringing you less than 25% of your money back.

So, if you’re concerned about taking a big risk by spending money on opening the CS20 case, hoping for that blue gem knife, there’s a safer alternative available below.

Method 2: Buy It from a CS:GO Trading Site

The simplest and possibly more cost-effective method to acquire a Classic Knife Case Hardened blue gem, with your preferred pattern, is by purchasing it directly from a CS:GO (CS2) trading site. This approach eliminates any reliance on luck since it’s a direct transaction between you and the seller. Plus, it only takes a few clicks to buy your desired skin and have it added to your Steam inventory.

Some people might argue you can get lucky and get a classic knife blue gem after opening the CS20 case one time, so getting you a valuable skin for just $3.09, but it’s extremely unlikely to happen, as the odds are less than 0.02%. 

So, there’s a higher chance you’ll end up spending thousands of dollars before getting lucky enough to obtain a Tier 1 classic knife blue gem. And even if you do manage to get one, you might only break even, resulting in no profit at all. Even if your goal is simply to add the skin to your inventory, it’s still not a wise choice.

Therefore, we recommend you to explore the following skins trading sites to find your classic knife blue gem:

• SkinPort
• SkinBaron
• DMarket
• CS.MONEY
• SkinsMonkey
• Tradeit.gg
• WhiteMarket
• GamerPay
• WaxPeer
• ShadowPay
• BUFF Market

They are the most reputable CS:GO trading sites with fair prices and plenty of active listings. Therefore, they’re your best choice when looking to purchase a classic knife blue gem.

We recommend you to explore them all, so you can compare prices and offers. Also, it’s worth noting that it will take work to find your preferred pattern, especially if you’re aiming at getting a Tier 1 classic knife blue gem, as they are very scarce.
