As I pointed out earlier my cheapest shavette($3) gives the best result.I get consistent DFS and sometimes a BBS with it.My swinglock($9) is awkward in comparison,the stainless steel slidelock with long blades ($15) one is just a cutter.Flesh,hair does not matter.The slidelock can't come apart so that should allay your fears.,I can see a very remote chance of that with a swinglock.Aligning the blades is no problem just slide the cutouts under the prongs pull or push it shut ,visually check the alignment.Apply to whiskers!
One day I may spring for a 40-50 dollar shavette but right now I am happy with my cheapie.
