the tools for fixing cars/to fix cars

[navi tasan]

Which are correct:
1) His suit to wear at official meetings is at the cleaner's but his suit to wear at parties is here.
2) His pen to sign official documents is on the desk, but his pen to take notes is in his pocket.
3) The tools to fix cars are in the garage, but the tools to repair electronic devices are here.
4) The tools to fix cars with are in the garage, but the tools to repair electronic devices with are here.

I think one would normally use 'for + gerund' (for wearing at official meetings, etc.), but I wondered if the infinitive could work.

None of them sound natural, I'm afraid.

1) The suit he wears to official meetings is at the cleaner's but the one he wears to parties is here.
2) The pen he uses to sign official documents is on the desk, but the one he uses to take notes is in his pocket.
3) The car-repair tools are in the garage, but the ones for electronic devices are here.
