Purchased as airplane carry-on permissible alternative to my preferred safety razor. I am unable to get a clean shave without painful and unsightly razor burn with the more widely-available multi-blade cartridge razors, and the few other single-blade alternatives (e.g., Bic yellow and white single-blade razors or generic store-brand equivalents) give me very poor and generally inconsistent shaves. Obviously this razor isn't going to perform like my Muhle or Rockwell razor with a Feather blade in it, but I find this much more comfortable and effective than any other disposable or cartridge razor than I have been able to find. Also, I have to admit, I kind of like having a pivoting head on a single-blade razor - haven't encountered this combination anywhere else, and I like it. I'd give this 5 stars as a substitute for a safety razor suitable for airplane carry-on, and still at least 3 stars and maybe 4 as a general use razor.
