Katana
Weapon · WeaponMelee3★Melee blade with an edge keen enough to cut a target down cleanly in one stroke.
Katana is 14th of 79 melee weapons by attack, at 1,014 against the 2,400 of Laser Sword.
Nothing is crafted from it — it is an end product, so anything you make is meant to be used rather than banked as a component.
Details
At 10 weight each it eats carry capacity fast, so bring a mount or park a chest nearby. At 98,480 gold it is worth real money to a merchant.

Where to Find Katana
The recipe is not on the Technology tree — it is locked behind a schematic you have to find first. The best single source is treasure map digs (tier 2) at 2.6% per container, and the table below lists every tier and where each one drops.
Every Tier of Katana
The same piece exists at 5 rarities, and the gap is not cosmetic: attack runs 780 to 1170, a 1.5x swing. Which one you end up with is decided by the rarity of the schematic you built from, not by the recipe — so a legendary copy of this is worth more than the next item up built from a common one.
Schematics That Unlock Katana
The Technology tree hands you the plain Katana at level 44 for 2 Technology points, but nothing above that base version — the rarer builds are schematic-only. One schematic grants the recipe, and they are world loot — chests, boss Pals and the late-game pools — rather than anything you research. Higher-rarity copies of the same schematic raise the quality of what you end up crafting.
Fastest route. The fastest route is treasure map digs (tier 2), and the reason is the ladder rather than the top rung: that pool stocks every tier, so the common copies it hands you fuse upward into the one you want. Counting them, a top-tier Katana schematic works out at roughly 56 containers against the 97 the 4★ drop rate alone suggests. Spare low tiers are progress, not clutter. Schematics fuse five-to-one, so a lower tier with better odds can beat the top tier outright. Counts are containers of that source, not time.
| Schematic | Rarity | Where it comes from |
|---|---|---|
 Katana Schematic 3 | 3★ | Treasure map digs (tier 2), Desert sea base camp stashes, Sakurajima treasure chests +9 more — best 2.6% (grade 3/5/6) · Supply drops in the Desert (0.51%) |
Alternatives and Upgrades
Beam Sword sits just above it at 1,023 attack — only 9 more, close enough that it is a sidegrade rather than an upgrade. The next real step is Lily's Spear at 1,075; below it is Katana at 936.
