Pair of jeans as a strop?

Discussion in 'General Shaving Discussion' started by Sir Walter of Mount Royal, Apr 27, 2011.

  1. I've seen several websites and youtube videos recommending to use an old pair of jeans to resharpen cartridge and DE blades.

    Won't that wear out the blades prematurely?
  2. Ive seen this in so many forums with people getting "great results"

    People claim to have used the same cartridge for months

  3. I did this once just for sh*** and giggles, but did it before my first shave. I noticed my third and fourth shaves were better than my first couple. It seemed to help a little bit. I used a very taut section of my bed on top of a stretched sheet. I may do it some more.

    Med Personna, btw
  4. In regards to cartridge razors, the stropping action on the jeans should accomplish nothing. Stropping requires that you have access to both sides of the blade edge, and the nature of the cartridge means one side is inaccessible.

    Yet people do claim results, it might be that the stropping action is not sharpening it, but is removing oxidation from the blade edge.
  5. I use a home-made denim strop with my straights. It was formerly a pair of blue jeans. It is an acceptable cloth element in my opinion.

  6. Best thing you can do to extend blade life is to keep it as dry as possible, so the stropping on cloth may work somewhat just by removing surface moisture.
  7. From what I understand, blade dullness stems more from oxidation, microscopic rusting, than from contact with whiskers. Corrosion cause metal on the blade to flake off and the edge to become blunted and jagged. That results in blades pulling and tearing hairs instead of cleanly slicing through them.

  8. When that article was written, blades were made with carbon steel. They are now made with stainless.
  9. Gillette blades made in the 1930's :

    Speaking from experience it works with carts. Haven't and probably won't try it with DE blades.
  11. Thank you for all the answers.
  12. The Kroman blades pictured above were a dismal failure for Gillette. They were rushed into production during the "blade war" with Henry Gaisman's Auto-Strop company and were not quite ready for prime time. Gillette charged 50% more for the blades, which were made from a chromium-manganese steel alloy. They did not perform as well as the old "green package" blades, but were the only blades that fit the NEW razors.

    After the Gaisman takeover of Gillette, they introduced the Blue blade which used the Probak manufacturing techniques and withdrew Kroman from the marketplace. Interesting that Gaisman continued used King C. Gillette's picture on the new Blue Blade package as it had been used on both the Kroman and the old green blades, and Mr. Gillette was no longer around . . .
  13. (Steel + chromium) x the right heat treatment = basic recipe for stainless steel.

    Kro-man = (steel + chromium + manganese) x wrong heat treatment = very brittle stainless steel = a big failure

    Because of the embarrassment caused by the Kro-Man blades, Gillette created the famous Blue blades, so that the consumer could be assured they weren't being sold some of the Kro-man leftovers.
  14. What effect would Corduroys have?

    Or Parachute pants?

  15. Corduroys would cause ridges so your face would look like someone went over it with a rake! OUCH! :ohmy:

    Parachute pants could only be used while in mid air descending to earth, so we would not see a lot of applications with that design! :tongue_sm
  16. so in essence, to strop a sharpened blade, with a cloth material is good, but a sturdy one such as denim or canvas is more conducive to maintaining a fine edge.

    Lesson of the day? if you're in a pinch...i.e. you're down to your last blade of the one million you aquired during your blade aquisition frenzy...take some denim to it.
