How do I check the pattern index of a Karambit Case Hardened?

In CS2, open your inventory, click 'Inspect', and look for the 'Pattern Index' field. Alternatively, use third-party databases like CSBlueGem.com. CSBoard displays the exact pattern index on every listing page so you can verify before buying.

Is it safe to buy a Karambit Blue Gem on CSBoard?

Yes. CSBoard is a P2P marketplace where trades execute directly through Steam’s official trade system. There are no bot middlemen, and all listings are verified. You can instantly cash out via USDT (TRC20, BEP20, Solana, TON) with no KYC.

What’s the difference between Tier 1 and Tier 2 Blue Gems?

Tier 1 patterns have 90–100% blue coverage and are extremely rare, commanding five- to six-figure prices. Tier 2 patterns (75–90% blue) are more common and trade 3–10× cheaper, making them accessible for most collectors while still offering strong appreciation.

Which float is best for a Karambit Blue Gem?

Factory New (0.00–0.07) commands the highest premium, but Minimal Wear (0.07–0.15) is often the sweet spot for value. Field-Tested patterns still look great and are far more liquid. CSBoard lets you filter by float range on every item page.
