Katana is a high-value melee weapon search; use the Katana page for route status, demo notes, and tier-list context.
Katana is a high-value melee weapon search. Demo-era data connects Katana to Shady Situation while helping Mayor Cutter, but full-game obtainment should be checked before treating that route as final.
Use the Katana page for current status, then compare it with the Tier List and Shadewood/quest pages before committing to a long route.
If you only need early survival, do not delay food, water, healing, and basic melee routes just to chase Katana.
