Knife Skin Rarities and Smile Coin Costs
Players acquire finishes for the knife through the dedicated cosmetic shop menu, holiday bundles, or seasonal crates. The cosmetic catalog divides knife finishes into defined rarities, each with standard Smile Coin price points.
| Rarity Tier | Cost per Skin | Selection Considerations |
|---|---|---|
| Common | 200 Smile Coins | Entry finishes like Red that cost minimal currency |
| Rare | 500 Smile Coins | Textured patterns such as Checkers and Pastel Rainbow |
| Limited | Free / Event-tied | Time-sensitive releases such as Pumpkins and Icicle |
The wiki documentation records 41 knife skins across all tiers, requiring 35,900 Smile Coins to collect in total. Common skins cost 200 Smile Coins each, while Rare skins cost 500 Smile Coins each.
Catalog Tiers and Summer Update Additions
The weapon customization roster features standard store tiers as well as special categories introduced in themed updates alongside broader weapon skins.
- Common and Rare Tiers: Common options include Red and the starter Default appearance. The Rare category contains textured visual patterns such as Checkers and Pastel Rainbow.
- Ultra and Legendary Tiers: High-tier cosmetic patterns include Flame and Ruby in the Ultra category, alongside Diamond and Shark in the Legendary category.
- Crystal Tier: The Crystal set features shard-based weapon textures, dividing variants into White Shard at Common rarity and Purple Shard at Rare rarity.
- Limited and Event Skins: Special distribution knives include seasonal patterns such as Pumpkins and Icicle. Update releases also add festive variants, such as the Halloween Crate and Spooky Bundle containing over ten themed Halloween skins.
The Summer update expanded melee styling options by adding the Pineapple, Watermelon, Overgrowth, Bubbles, and Shark skins across Shotguns, Knives, and Bats. Players equip and rotate these patterns directly within the dedicated cosmetic selection menu.
Knife Combat Mechanics and VIP Access
The knife functions as one of the essential close-range weapons for surviving encounters with infected opponents. Achieving the in-game badge titled "Obtained All Weapons In One Life" requires carrying the knife alongside the Bat, Bottle, Hatchet, Handgun, Shotgun, Ice Potion, and Invisibility Potion in a single run.
Players with the VIP game pass receive an automatic knife spawn on a 15-second cooldown timer. An update setting gives pass holders the option to toggle this VIP spawn bonus on or off directly through their settings. Balance changes from the Summer update also reset weapon cooldown timers immediately upon using an escape tool, allowing for faster defensive reactions during close-quarters combat.
