If you are filling out a Gamma-era knife loadout or want a cool-tone blade without flashy particles, Clear Water (hy_ocean_knife) is one of the straightest themes in the knife pool: full-surface blue camo hydrographic, name and palette both read “clean ocean.” This guide is for inspect-first buyers—not a lore dump.

Release anchor

June 15, 2016 — Valve shipped Gamma Exposure. Clear Water went live that day and entered Gamma Case drops. When you sort inventory by update wave or verify “same batch as Gamma content,” that date is the hard pin. Wrong era = wrong expectations on supply and pricing context.

Box source (non-negotiable)

Gamma Case only. Two paths:

• Unbox: variance and case cost.
• Secondary: C5GAME or Steam Community Market — filter by wear tier and knife model, then compare like-for-like.

Fixed box source makes haggling and duplicate checks easier; do not assume it drops elsewhere.

What you are actually buying

| Fact | Detail |
|------|--------|
| Slot | Knife |
| Finish | Clear Water |
| Rarity | Rare |
| Style | Hydrographic (water transfer) |
| Wear | 0.00 – 0.50 (Factory New through Battle-Scarred band) |
| Designer | Valve |

Official line: blue camo coating pressed across faces via hydro. Different knife models (curve, surface area) shift how camo blocks read in inspect—normal, not a “bad pattern roll” in the float sense.

Wear behavior: At low float, blue panels stay cohesive and the “fresh water” vibe holds. As wear climbs, scratches and base metal eat the calm look—still playable if you like beaters, but not the same skin visually. 0.0–0.5 is wide; use it to tier-shop instead of blindly chasing FN on every model.

Inspect checklist (do this before pay)

1. In-game inspect on your target knife model—screenshots lie about seam placement and face coverage.
2. Pick a wear cap first: “clean inventory” → prioritize lower wear; “budget flex” → mid or upper band can look fine on some silhouettes.
3. On C5GAME / Steam, sort by float band, then open inspect links—compare block direction side by side.
4. Pairing: blue camo plays nice with cool gloves and minimal loadouts; no animation tax, so budget goes to float and model, not effects.

Shop verdict

Worth it if you want a Gamma-linked, low-noise blue knife and you will inspect on the exact model you plan to buy. Skip or downgrade wear if you need mirror-clean blues at a distance—hydro camo will muddy as float rises.

Value tip: Because wear spans 0.5, FN/OH alternatives on the same listing often beat overpaying for marginal FN gains—especially on models where camo already breaks up.

Expert muttering

Gamma date plus Gamma Case is a boringly good provenance story—use it when sellers blur “old blue knife” listings. Clear Water is Valve hydro, not community hype; the market premium is mostly nostalgia + color match, not flex FX. I still tell everyone the same thing: static CDN images are for mood only—the 3D inspect at your float decides buy or pass. If two listings share a price, take the one whose camo flow matches how you hold the knife in inspect, not the one with the prettiest thumbnail.
