Shave Kit

How to shave in flight? It razors (, knives, etc.) allowed in international flights?

I have to shave my beard every day, as many of them turned gray. But for the international flight (which lasts approximately 25 hours), how do I shave? Are knives, razor blades, shaving cream allowed in international flights? If not, how can one shave in flight?

Safety razors and less than 3 oz cans shaving cream are allowed and many airlines offer business class and 1. Simply go to the bathroom and shave, usually I bring along a electric shaver on long flights, it is much easier than foam and razors in the bathroom of the cramped plane. Shavers electrical and safety are not permitted and are perfectly fine to carry on an airplane, at least in the U.S. and Asia where they fly and often. http://www.tsa.gov/travelers/index.shtm
