00Why patterns matter

Every ★ Kukri Knife | Case Hardened · Blue Gem has the same paint_index — but the pattern seed (0–999) controls exactly how the dye lands on the blade. Two listings can have the same wear and float but look dramatically different.

The cards below compare a typical Unranked roll (seed #235) against the Tier-1 hero we picked (seed #844). Same skin, same phase, same wear band — pattern is the only difference.

Why this mattersBoth knives share identical Steam metadata — Steam treats them as the same item. But buyers who know patterns will pay a premium for the T1 because the visual is unambiguously better. Pattern guides like this one make that premium visible.

About Blue Gem patterns

The Kukri Knife is one of CS2's newest blades (Kilowatt Case), and its Case Hardened follows the familiar marbled blue-and-gold steel finish on a wide, curved blade. The seed decides the blue coverage; the bluest rolls are the Blue Gems.

Seed #494 leads the Tier-1 Kukri Blue Gems — a group that also gathers #770, #575, #652 and #618, all seeds where blue floods the broad kukri blade with little gold bleed.

01T1Tier 1 — Best patterns

What makes a T1

The best patterns in this skin. Tightest symmetry, deepest coverage, and the visual hallmarks that separate top-shelf examples from everything else.

02T2Tier 2

What makes a T2

Very strong patterns — close to T1 quality but with one or two visual compromises (off-axis tip, slightly less coverage, or a less symmetric back).

03T3Tier 3

What makes a T3

Above-average patterns. Recognisable as "good" but with a clear weakness compared to T1/T2 — useful for buyers who want a hint of pattern premium without paying T1 prices.

What makes a T4

The lower end of curated patterns. Still better than a random unranked roll, but the visual differentiator is subtle.

Everything else — Unranked

The remaining ~782 paint_seeds fall outside the curated tiers. They make up the bulk of Phase 1 supply on every marketplace and don’t carry a pattern premium — what you see is what you get, like the baseline reference (seed #235) we used at the top of this guide. If a seed isn’t listed in T1–T4 or BTA above, treat it as Unranked.
