Answer
Crowbar is a melee weapon and route-utility search; use the Crowbar page with map context before following old demo routes.
Crowbar is a Piggy: Intercity melee weapon/search target, but a fully verified current full-game location is not listed as final on this site yet.
The useful action is to open the Crowbar weapon page and map pages together: look for route context, quest relevance, and whether the page has been updated after the latest build.
Do not blindly follow demo-only crowbar routes unless the same route is confirmed in the current game.
