Case Hardened on knives is one of the easiest finishes to recognize from across the lobby—and one of the hardest to buy well. The same paint name on a different blade profile reads completely different; on the Shadow Daggers (weapon_knife_push), you’re judging two short blades at once. This listing is mythical, Patina craft, wear 0.00–1.00, internal aq_oiled, shown in-game as knife | Case Hardened. If you skip in-game inspect and wear checks, you’re not “saving time”—you’re rolling dice with someone else’s screenshot.

Release & pedigree

17 September 2015, Shadow Boxing update—same moment as the Shadow Case. For collectors, that date matters: this isn’t a later re-drop; it’s part of the Shadow line’s launch story. Valve’s blurb is blunt: charcoal and high heat produce the colored case hardening, and a little extra color at the edges is normal—randomness is the product, not a defect.

Where it drops

Shadow Case only. On C5GAME or the Steam market, filter by case origin if you care about provenance; “open Shadow, hit knife, pray for Case Hardened” is still how a lot of veterans price these in their heads.

What actually moves the price

| Factor | Why it matters on dual daggers |
|--------|--------------------------------|
| Pattern placement | Blue/gold/purple clusters on which segment of each blade |
| Left/right balance | Symmetric bodies punish lopsided rolls |
| Wear tier | Patina + Case Hardened: low wear stays vivid; high wear dulls and ages fast |
| Float honesty | Page float must match the item you inspect—Patina makes mismatches obvious |

Copper-green Patina adds an oxidized, slightly vintage read on top of the random color blocks, so two items in the same wear band can look a tier apart if the pattern lands clean vs messy.

How to buy (shop workflow)

1. Always inspect in-game—see where the color sits on both faces, not just the hero side of a listing image.
2. Compare symmetry—if one dagger carries the “good” blue and the other looks washed, you’ll notice every round.
3. Match wear to your goal—play skins often favor mid floats that still read color; display pieces chase low wear with strong pattern.
4. Cross-check C5GAME and Steam—same float and pattern language, different fees and liquidity; pick the venue that fits how fast you need to move the item.

Shopping verdict

Worth it if you want a Shadow-themed knife with real 2015 case history and you’re willing to spend time on pattern—not if you want a “set and forget” knife that looks the same on every copy. Skip impulse buys off static “lots of blue” marketing; Case Hardened on short dual blades is a pattern SKU, not a uniform finish.

Budget tip: A balanced “good enough” pattern at a sensible float often beats overpaying for hype screenshots you never replicate in inspect.

Expert muttering

• Same finish name, different knife shape—never use another knife’s Case Hardened tier list as gospel for Shadow Daggers.
• Valve literally told you edge color happens—don’t treat mild border tint as a bargaining chip unless it’s extreme.
• Building a Shadow shelf? 2015 date + Shadow Case + Valve authorship fills the “era” slot better than a random later knife ever will.
• Mythical rarity doesn’t save you from 0.99 battle-scarred sadness—Patina will happily look tired at the top of the float range.
