If i'm only training one sword I usually send them straight to world 4, usually the team can carry them from the very first level (world 5 is more hazardous as there are a lot more arrows/catapults/bullets flying around that may heavydamage your level 4 sword in one shot lol). Even if I'm training more than one, having one speed-boosted oodachi that is a higher level than the rest of the team (so it attacks first and destroy 2 or 3 enemies at a time no matter what) and one other good sword is usually enough to carry everyone through world 4. I only go through world 1-3 if I'm training an entire team but usually I don't have that kind of patience...

After that it depends on the sword, an oodachi can hold its own on a team from level 15, for a tantou it's much, much later...
