3D preview: provider and limitations

Clicking 3D connects to cs2inspect.skin and shares your IP address, site origin and the skin, float and pattern shown here, not your Steam account or inventory. Models can use several MB. No 3D connection is made before you click.

Browser render, not CS2: lighting and wear can differ slightly. The pattern seed places the pattern as in game; check in game before you buy.

How these numbers work

All values are the blue share on the play side, from the same per-seed data as the checker. Top 1% from is the 10th best of the 1001 seeds and Top 10% from the 100th best: a seed at or above it is in that group. The median is the middle seed.

Lowest price is the cheapest copy we track in any exterior and any seed (Skinport, as of Nov 4, 2026); a good seed costs more. The top-10 row looks for this skin's ten best seeds on sale once a day.

About Gut Knife | Case Hardened patterns

The Case Hardened texture mixes blue, purple and gold, and the paint seed decides which part lands on the Gut Knife. Measured on the play side, 0 of the 1,001 seeds are Tier 1 (90% blue or more), 0 are Tier 2 (80-90%) and 6 are Tier 3 (70-80%); everything else is a regular pattern.

The seed is printed on the item in game and on every marketplace listing, so a pattern can be checked before buying: paste the inspect link above, or type the seed into the checker.

FAQ

What is the best Gut Knife | Case Hardened blue gem seed?

Seed 567 has the most blue on the play side, 73.9%. 0 of the 1,001 seeds reach 90% blue and count as Tier 1.

Which side of the Gut Knife counts?

The play side, the side facing you in game. The back side is measured too and shown next to it, since some seeds are blue on one side and gold on the other.

How do I check a Gut Knife | Case Hardened seed in CS2?

Type the seed into the checker or pick one from the table, then press Inspect: Steam opens Counter-Strike 2 with that exact seed on the skin, no item needed. The listings button finds that seed for sale on DMarket or CSFloat.

Does the float change the pattern?

No. The seed fixes where the texture sits and the float only adds wear on top, so the seed looks the same at any float. Scratches can hide colour on a worn copy, which is why pattern buyers usually want a low float too.
