I traveled for the first time last week with some razors - a GEM 1912 and an OCMM. I knew not to have a blade in them and mailed one to myself at the hotel where I was staying. So far, so good. When I went through security, my bag got pulled aside for further inspection. I waited patiently for an agent to free up to inspect it. The woman in front of me had nearly every article of clothing inspected so I wasn't looking forward to the process. Before the agent opened the bag I told him I suspected it got pulled because of the razors and assured him there were no blades. He found them quickly and looked inside the heads to verify they were empty (but was a bit mystified by the half spine shim in the 1912 - thanks Billy! ) He then had some great advice for me. He suggested that the next time I travel that I simply separate the razors from my luggage and run them through the detection machines on their own. I did exactly that on the return trip. No one looked twice at them and I was on my way. Good advice for all travelers who like to move through the lines quickly!
