About Blue Gem patterns

Huntsman Knife Case Hardened carries the marbled steel finish on a large, straight blade — a canvas that shows a clean blue play side off well. The seed decides the coverage; the bluest rolls are the Blue Gems.

Seed #618 is the #1 Huntsman Blue Gem and one of the most valuable Case Hardened knives in the game — the top example, owned by Krieke, sits in the $15–20k range. Tier 1 also includes #652, #721 and #29.

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 ~869 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 #0) we used at the top of this guide. If a seed isn’t listed in T1–T4 or BTA above, treat it as Unranked.
