LPT: On the road, with only a cheap disposable hotel razor? Use a cheap disposable hotel toothbrush to clean out the hair fragments between every few strokes. Much cleaner and quicker shave.

Title pretty much says it all, razor companies advise against this but this isnt some Giletto Fusion-X Magno-vibro Pikachu-shaver, its just a cheap razor. You're not taking it with you and need to shave. Bam.
