Case Hardened Tier List — Blue Gems by Weapon

Community tier lists grade seeds by blue coverage on the playside — the side you see holding the weapon. Tier 1 is near-solid blue; each tier down shows more gold breaking through. Backside coverage is tracked separately and trades at a discount. Because tiers are per-model, always check the list for the exact weapon: a grail seed on the AK-47 means nothing on a Bayonet.

The most collected Case Hardened item in the game. Pattern 661 — the famous "scar pattern" — is widely regarded as the #1 playside blue gem, with 955 and 670 close behind on most lists. Top-tier AK gems trade at large multiples of an ordinary Case Hardened, and StatTrak examples multiply again on scarcity.

Home of the most famous pattern skin in CS2: the Karambit 387 blue gem, whose owner has reportedly declined seven-figure offers. Below the grails, the Karambit's curved blade shows blue dramatically, which keeps demand strong across its upper tiers.

The budget entry into blue gem collecting — the slide shows a large, flat playside, so top seeds look striking, and prices sit far below AK or knife gems. A common path: learn the market on Five-SeveN gems, then move up.

Case Hardened rolls on most knife models — Bayonet, M9, Flip, Gut, Butterfly and the newer lines — each with its own seed list and its own collectors. Blade shape decides everything: a seed that pools blue on one model scatters it on another, which is exactly why per-item lists exist.

Four inputs, and they multiply rather than add. Playside coverage is the headline — how much of the visible face the blue occupies, which is what every tier list is really ranking. The model is next, because the same tier is a different amount of money on an AK-47 than on a Five-SeveN, and different again on a knife. Wear is third and it is not a rounding error here: the blue desaturates as float climbs, so the effect you are paying for reads less clearly on a Field-Tested than on a Factory New example of the identical seed. Scarcity extras come last — StatTrak versions exist across much of the family and sit in a far smaller population, so a tiered seed that is also StatTrak is a thin market on top of a thin market.

This is one of the few finishes where two listings of the same item, the same wear and the same price can be worth wildly different amounts — and the market reflects that unevenly. Most sellers price by item name and wear, exactly as they would for any other skin, because checking a seed against a per-model tier list is work nobody does for a routine listing. The collectors who do check are a small group relative to how many Case Hardened items are in circulation, which is why tiered seeds surface at ordinary prices more often than the family's reputation suggests. The flip side is on the way out: the buyers who pay a gem premium are that same small group, so a top-tier seed is usually quick to buy and slow to sell. Budget patience, not just money.

A short checklist prevents most of the expensive mistakes. Confirm the tier against the list for that exact model rather than a general Case Hardened list. Open the inspect view and look at the playside yourself instead of trusting a marketplace thumbnail, which frequently shows the other face. Read the wear alongside the seed, because a top-tier pattern on a Battle-Scarred blade is a different product from the same number in Factory New. Ask which list a seller is quoting when a claim looks borderline — lists genuinely disagree in the middle tiers, and honest disagreement is the common case rather than a scam. And treat a price that looks too good as a question rather than an answer: nine times out of ten the wear, the face or the model is not what you assumed.

The hard part of blue gem hunting is not deciding which seeds you want — the lists above settle that in an afternoon. It is being present in the minutes when one of them appears at an ordinary price, on whichever marketplace its owner happened to use, which is a thing no human does reliably. That is the part CSWatcher takes over: name the seeds and the items you care about, and it watches for them around the clock across every marketplace it covers, then tells you the moment one lists inside your price. On CSFloat it can go a step further and complete the purchase for you within a spend ceiling you set; everywhere else the alert hands you the listing and you buy it yourself.
