Overview
Thousand Edge (Knife evolution) fires one blade per Amount at cost 0, making it a direct Amount-scaling S Tier weapon. On Giovanna (Jennaro), whose passive continuously increases Amount, this becomes one of the highest sustained-damage weapons in the game. Amount 30+ reaches screen-clearing levels against both mobs and bosses simultaneously.
Evolution Recipe
Knife + Bracer → Thousand Edge
Bracer increases hand size before evolution, providing card management value from the start.
Recommended Gems
Priority:
- Wild — flexible 0-cost chain placement
- Triple Damage — multiplies across all launched blades (Amount × 3x compound)
- Amount-up — directly increases blade count
- Yin-Yang — draw support
Amount-up gems have higher priority here than on most weapons — every extra blade is a direct damage multiplier stacking with Triple Damage.

Tips
Secure Knife and Bracer early. Stack Amount cards and abilities before evolving to maximize blade count immediately post-evolution. Place as the 0-cost front position in the combo staircase — delivers continuous blade rain for wave clear and boss damage simultaneously.
Amount management is the core skill of this weapon. With Giovanna pushing Amount beyond 30, Thousand Edge becomes the most efficient sustained-damage weapon in Vampire Crawlers.
