All CS2 M9 Bayonet Case Hardened Blue Gem Patterns: 601 and Tiers Explained

In CS2, every Case Hardened weapon has 1,000 different Patterns that define how much of the skin appears blue. The more blue on the body of the skin, the more valuable it is, with collectors looking for the Patterns that are as close to completely covered as possible. As one of the most popular knives in the game, the M9 Bayonet is no different in this regard. The M9 Bayonet Case Hardened Blue Gem is a sought-after CS2 knife, although it can be quite expensive for the right buyer.

To help you find out which ones you should be looking for, I’ve put together an M9 Bayonet Case Hardened Blue Gem Patterns guide, showing you every tier commonly agreed upon by the CS2 community.

M9 Bayonet Case Hardened Blue Gem Tier 0: 601

The CS2 M9 Bayonet Case Hardened pattern 601 is considered by the community to be the definitive Blue Gem for this particular knife. It’s nearly a perfect blue throughout, with only a bit of the yellow rust of the knife seen along the bottom. Considering it can cost upwards of $75k in high wear ratings, the Pattern 601 M9 Bayonet Case Hardened Blue Gem will be out of range for most players, but it’s undeniably beautiful to stare at longingly.

M9 Bayonet Case Hardened Blue Gem Tier 1

All of the CS M9 Bayonet Blue Gem Tier 1 Patterns aren’t quite perfect, but you’d still consider them to be among the top-tier options for most players. Remember – all of these patterns are different, and each will have something unique holding them back from being on the same level as the 601. Still, the Blue Gems are very blue, and the high price of these options will reflect that.

• M9 Bayonet Case Hardened Blue Gem Tier 1 Patterns: 58, 107, 150, 239, 253, 349, 354, 403, 406, 417, 449, 503, 517, 523, 550, 585, 634, 675, 897, 946

M9 Bayonet Case Hardened Blue Gem Tier 2

When it comes to the CS2 M9 Bayonet Case Hardened Blue Gem Tier 2 Patterns, expect to see a lot more of the standard yellow rust color on these options. Yes, they’re still Blue Gems, but this is where you should really start to see the price come down. On a lot of the Tier 2 Patterns, the blue will often be interrupted a lot more by purple hues, which isn’t ideal for collectors looking for something clean.

• M9 Bayonet Case Hardened Blue Gem Tier 2 Patterns: 21, 91, 117, 166, 167, 202, 224, 269, 281, 288, 336, 346, 355, 366, 430, 613, 628, 715, 793, 813, 867, 880

M9 Bayonet Case Hardened Blue Gem Tier 3

The CS2 M9 Bayonet Case Hardened Blue Gem Tier 3 Patterns are where things start to get messy. The blue sections will appear more splotchy rather than covering wide areas, but this can produce interesting patterns in their own right. The prices of the Tier 3 M9 Bayonet Blue Gem Patterns also start to resemble those of the standard skins, so you can snag a bargain with some of these.

• M9 Bayonet Case Hardened Blue Gem Tier 3 Patterns: 4, 41, 59, 88, 108, 124, 141, 157, 173, 204, 210, 227, 229, 243, 249, 286, 293, 295, 298, 319, 345, 356, 372, 393, 476, 490, 525, 529, 533, 546, 553, 598, 610, 790, 821, 837, 859, 866, 887, 908, 910, 915, 933, 959

M9 Bayonet Case Hardened Blue Gem Tier 4

If you want a Blue Gem without having to pay true Blue Gem prices, then the Tier 4 patterns for the M9 Bayonet Case Hardened Blue Gem could be right up your alley. Don’t expect anything special, here – the tips of the knives are often rusty in these Patterns, and the blue areas are similarly sparse like the Tier 3 options. You should take a look at some of these for yourself to see if they’re “Blue Gem” enough for your taste.

• M9 Bayonet Case Hardened Blue Gem Tier 4 Patterns: 2, 63, 64, 97, 103, 113, 136, 138, 156, 162, 176, 177, 179, 209, 246, 251, 292, 308, 351, 353, 369, 401, 413, 445, 473, 475, 496, 506, 507, 516, 518, 524, 526, 556, 564, 573, 619, 632, 651, 674, 681, 698, 706, 735, 759, 764, 779, 783, 794, 808, 811, 835, 869, 871, 902, 904, 916, 941, 963, 968, 989

Why is the M9 Bayonet Case Hardened Blue Gem so rare in CS2?

It’s simple: odds upon odds. First, you have to open one of the 11 cases that drop the M9 Bayonet Case Hardened Blue Gem.

Even further, it has to be a Case Hardened knife, which is extremely unlikely. Even if all of those things work in your favor, there’s then the chances of it being one of the Blue Gem patterns listed above. With all this working against you in tandem, it’s a miracle that any CS2 M9 Bayonet Case Hardened Blue Gems exist at all.
