Just scored me a Gem Featherweight for 3 bucks at a local antique store nearby. Cleaned it up 'til it was nice and shiny and gave it a run. Great shave. Did 2 wtgs instead of 1 wtg and 1 xtg, which is what I usually do, but am waiting for my shavette gash from about three weeks ago to heal up completely before I do xtgs again. Compares to the Micromatics I used to have, maybe even smoother. Have plenty of Gem Personna SE blades, but am tempted to try carbon ones to see if they are any smoother, like Pal or Treet. Has anyone on here have any experience using carbon SE's? I hear they are sharper, but dull quicker, and have to keep them high and dry. If anyone here has used carbon SE's, please let me know. Also, let me know would it be worth ordering in bulk from Ted Pella should in the event I become a dedicated SE user, and what type would be best, PTFE or carbon?
