Primidi 1 Pluviôse an 233 de la Révolution, jour de Lauréole

  • Preshave: Proraso White Preshave
  • Brush: Zenith 506U XS Horse 🐎
  • Razor: Feather Artist Club SS Kamisori
  • Blade: Feather Pro Guard (9)
  • Lather: Le Père Lucien Bay Rum
  • Postshave: Naissance 702 Witch Hazel
  • Postshave: Pitralon Classic After Shave
  • Postshave: Nivea After Shave Balm

I used the kamisori shavette today – no slippage. The shave with the shavette is quicker, but less close. Also, this blade starts tugging, so I may get rid of it soon.

@gcgallant@sub.wetshaving.social: I screwed up and responded to myself, rather than to you, but here are the photos. I don't know if you see anything.

At this time I'm wondering whether putting the lower part of the kamisori blade into a (padded) vice might be able to straighten the thing back?

Anyways, have a good evening!

Unfortunately it's not that simple. You have to overcome elasticity, which means that in needs to be bent back more than just straight, so that in plastically deforms in the precise way that makes it straight again after unloading. Predicting the right deformation (i.e., this exact problem) is a difficult computational dark art in deep drawing. Also, you only get a few chances, because plastic deformation leads to work hardening (it's like you're forging the steel locally where it deforms).

To illustrate the problem, you can bend a straight piece of hardened wire like a bicycle spoke and try to straighten it again. It's almost impossible, because the exact location of your original bend has work-hardened and when you try to revert it, typically a part next to the original bend will bend instead.

Well, I never knew I wanted to understand why that happened, but apparently I did. Fascinating.
