How to Get This W-Engine

Pull it from Signal Search using Master Tapes / Encrypted Master Tapes (bought with Polychrome) — S-rank W-Engines get their own banner, usually alongside the matching character's banner.

Trade for it at the Gadget Shop's Box Galaxy section (Sixth Street): costs W-Engine Components + W-Engine Chips + Denny; Chips come from disassembling spare W-Engines.

A handful of A/B-rank W-Engines unlock through Proxy Primer trials or as story/event rewards instead of the gacha — not every W-Engine is pullable.

Official Artwork / Lore

This W-Engine's design was originally much more modest. The focus during its creation was on offensive capability and stealth until its owner met a group of curious and loud individuals who had no concept of subtlety. Not only did they put flashy stickers on it, but after injuring their fingers, they often used it to cut ropes, open boxes, and even slice through sticky tape... "That... yeah, that box cutter, lemme borrow it, thanks!" "Boss, it's not a box cutter, it's called Hidden Claw!" "Hey, Kitty, lemme borrow your box cutter!" "It's not a box cutter, it's called Hidden Claw!" "Mind if lil ol me takes your box cutter for a mo?" "..." "Fine, it's a box cutter. Whatever makes you happy." — Pulchra

How to read this W-Engine page

Every W-Engine has 5 Refinement ranks (R1→R5): refinement ONLY strengthens the passive effect — the numbers in the table above run from left (R1, unrefined) to right (R5, max refinement via 4 duplicates or Overclock materials); Base ATK and the Advanced Stat (CRIT Rate/CRIT DMG/ATK%/PEN Ratio/Anomaly Proficiency...) do NOT change with refinement, only with the engine's level. "Best Agents for this W-Engine" prioritizes agents whose real build actually recommends this engine; if that data isn't available yet, the page falls back to agents sharing the same specialty as a rough guide. "Alternatives of the same specialty" lists other W-Engines with the same role — useful when you don't own the engine shown on this page.

FAQ

What is Box Cutter in Zenless Zone Zero?

Which Agents should use Box Cutter?

How much Denny and material does it take to upgrade Box Cutter, and where do I farm it?

Leveling Box Cutter through every milestone takes roughly 4 W-Engine components and Denny ×320,000, Stun Component ×3, Reinforced Stun Component ×26 Denny combined — the components drop from Combat Simulation; see the exact breakdown per milestone and the Battery cost in the "How Much You Need" and "Where to Farm" sections above.

Is Overclocking Box Cutter worth it?

Overclocking only strengthens Box Cutter's passive effect from ★1 up to ★5 (5 copies) — it never changes Base ATK or the sub-stat, so getting the base copy matters far more; treat extra copies as a bonus.

Where do I get Box Cutter?

Mostly through Signal Search gacha (Polychrome); a few A/B-rank W-Engines are tradeable at the Gadget Shop's Box Galaxy or come from story/event rewards — see the "How to Get" section above for details.
