There is no way to get sword "legally" in umoded game. You can get:
Crowbar: In mission 10 on airport
Wooden plank: In mission 7 - Sarah
Steel bar: I think it's in mission 9
Bucket: in steamboat mission
Dog's head: Just let explode grenade near dog
There is no way to get sword, flashlight and bottle in unmoded game. All of that (expect of sword) are useless.
