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.
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?
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.
You can still try to fix it, I’m just saying that simply putting it in a vise won’t straighten it. You need to bend it further than straight, but not too far because it gets more difficult to straighten the more load cycles you put on it
I forgot you already own a kamisori-style shavette in my recommendation yesterday. Oops.
Personally I feel like Feather AC blades are not really comparable to their DEs, at least for me. The ProGuard are the only usable ones, but they are harsh despite the guard comb. I feel way more at ease with KAI ACs, either the “Captain Pink mild” or the guarded “Protouch MG” are very nice and comfortable blades.

@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.

Anyways, have a good evening!

Not looking good, I see 😩
Oh, and for the record, I would definitely try, if it were my razor, and I wouldn’t be surprised if it turned out good enough
I willdefinitely give it a try, but I’m wondering if reaching out to the head of River Razors is the best option 🤔
Maybe that’s a good option, yes.

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

I also generally prefer the Kai’s, but I had this one in the shavette, so I’m using it 🤷
Understandable, I wouldn’t want to waste it either!
