You have everything packed. Trousers, toothbrush, passport. The plane tickets are in your bag, and you arrive at the airport, ready to check in. But how is it with your razor? Can you bring it along in your Carry On bag? Or do you have to check it in?
In fact, the answer is simple – but it also depends on the type of razor you’re using. So let’s just take a minute to recap what you can or cannot bring through the airport security.
Razors and blades
Cartridge Razors like the Gillette Fusion, Schick Hydro or any other safety razor, where the blade is mounted in the head and cannot be taken out easily ARE ACCEPTED as carry on luggage. Spare blades for this type of razor is accepted as well.
Safety razors, like Double Edge Razors and straight razors, where the blade is NOT fixed in the head are accepted, as long as it doesn’t contain a blade! But then again – why not just put it in the checked in luggage along with the blades.
Double Edge blades, Straight razor blades and similar, where the blade is NOT embedded in a cartridge ARE NOT ACCEPTED as carry on luggage. These must be checked in at all times.
So – for business travelers carrying only a small cabin bag and no checked in luggage, the best solution would be to bring a safety cartridge razor or disposable razor – and leave the DE razors at home.
Liquids
You should also remember the 100ml limitation on liquids that apply to all flights in US and Europe. Any containers of liquid that can hold more than 100ml can be rejected by the airport security and confiscated.
Having said all that – I wish you all a happy summer and a safe journey. And for myself? Well – I think I’ll just drive my way to Holland this summer! 
Why not just pack your favourite DE and pick up some blades when you reach your destination? One of the beauties of DE shaving is that the blades are so cheap that it doesn’t matter if you use the whole pack or not.
