I was interested to know if you are allowed to pack a small knife in your main luggage as I am going to be travelling across asia from March 2012 and a knife would be a useful tool to have.Anyone Know ? 
Do airports allow you to pack a knife in your main luggage ?
It should be fine in your main luggage - I normally have a swiss army knife or leatherman when I go away.
Luggage is xrayed - it might raise some eyebrows?
It should be fine. Some places may make you fill out a pre-departure declaration form - which is also required at the arriving airport - just ask at the declaration/security desk. But this only occurred when travelling with a set of 15 kitchen knives in our bag.
"main luggage" is that checked in luggage, or carry on luggage? There's a rather big difference between the two If the first, you should be fine, if the latter, you will lose it when they scan your carry on at check in.
Ditto above.
1.) A small knife is no issue in your checked luggage.
2.) It's (obviously) not allowed in your carry-on.
That said, if you're only interested in bringing a small knife (and not an expensive one or a multi-tool like a Leatherman) then why not simply buy a cheap one in your arrival country? That would allow you to travel with carry-on luggage only.
Cheers,
Terry

No, I don't think so. Any airport wouldn't allow that.
I travel with this cool little Swiss army knife key I usually put it in my checked luggage, but often forget and it travels in my carry on, clipped on a key ring holder. Its never been spotted in the x ray, as I guess they think its a key. I figure if someone tries to hijack the plane with a box knife, I'll be ready to take them out!
paulmacpaul @ #7: That's incorrect.
Dodger @ #8: I had one of those on my key chain for years. To be honest I never found it very useful, but every now and then it handled some small task. In hundreds of flights it never raised an eyebrow until a couple of months ago - some goof in Vancouver Airport spotted it during a hand inspection of my carry-on and confiscated it. I argued but to no avail. I'm sure it's now on his keychain... twit...
