I have carried a knife on me, but never a razor blade. I can’t even imagine putting it into my hair. Guaranteed the only person to get sliced up would be me.
I carry money in my bra sometimes, or an ATM card. Not an ample roll of bills, for heavens sakes, but a single bill or a couple of dollars. The ATM card is easiest - it just slides between your breast and bra, half sticking out, easy to access. And I don’t do it on hot days, sweaty bills are just gross.
Anyone who wants to see a cheek razor fight should check out the french film “A Prophet.” Intense.
I assumed straight razors were used because they were widely available.
The only use I heard of for razor blades is to put a wooden matchstick in the slots and palm it, with the edge sticking out of the palm side. Then you slap your assailant’s face and draw, making a big nasty bloody cut.
Rather a lot of preparation for a non-disabling wound, and at least dangerous to the cutter as to the cuttee, so I wouldn’t recommend it.

Scottish squaddies are (used to be?) notorious for sewing bits of razorblade so that they just peeped out of the very front of their Glengarry, which they would then whip off and swing by the ribbons at the back to make an apparently ridiculous weapon in a fight - you’d be too busy laughing at the guy spinning his hat to realise you’d been cut to shreds. Apparently. I’ve never fought a squaddie, and can’t find any cites for it, but I’ve heard it from several people who are/were in Highland regiments.
Indeed; a +1 gun would allow you to bypass DR 5/magic, for instance.
Well, for 6 charges.
…and in other retractions, I humbly apologize for insulting the country of Wales. It seems like a really nice place, I’d like to visit it someday, and I don’t want to get shivved by Charlotte Church. Well, I suppose its all negotiable really.
Vital organs or no? Bleeding? Over nice clothes or old jeans? There’s a lot to consider.
Don’t they carry guns?
I carried a box cutter when I would go out running in my parent’s suburban neighborhood at night. My father insisted because he knew something I didn’t at the time - that there had been a couple of rapes in the neighborhood. I was never accosted by anyone, but then at 6’1" and very athletic looking (at the time), I might have been too intimidating to be a target.
I do and I am a respectful woman living in the city.
I just place one on the top of my head under a hair pen and layer of hair. I know a couple of other bartenders that do the same.
Mines a double edged bread scoring razor sharp to a T.
Its also for slicing a specific area of a man…. If you did not know otherwise. Now you do.
Unless you can make it to the throat. 
(Gross but true)
I never have nor, as far as I know, have any of friends. I’m with @aruvqan, if I’m going to carry protection, it’s going to be a gun.
Never mind
Michigan allows the carry of knives, all
kinds even switchblades. Though local jurisdictions can and do prohibit some kinds. Maybe that’s when razor blades go into coiffures.
Me and my friends when on our 20’s always carried these puny little knives when driving alone. Ridiculous when I think about it but it gave some comfort. If I decided to carry any type of blade now it’d be a switchblade. But overall I find what it could potentially do as gross and not sure if I could cross that line if the need arose.
I had understood from the recent knife-fighting thread that the first rule of knife fighting is not to get in a knife fight: run away. But if you are in a knife fight then you are fighting with a deadly weapon and need to be ready to kill your opponent, and for that you need a real knife, not a “puny little knife”/razor blade
Of course (some) people carry various Swiss army knives, keychain-sized ju-jutsu rods, steel hairpins, etc; why not a switchblade or razor blade, but who knows if you could rely on such a thing if your life depended on it.
I actually clip a small flick knife onto my left bra strap, if one is grabbed from behind, one can while doing the whole get a hand to protect the neck, take the knife and do damage to the attacker [have practiced it on the husband to make sure I can still do it from a wheelchair. ]
“The Pen knife is a very versatile tool. No one sees it coming.”
Neither have I. Neither of my two wives (no, not at the same time) have done this, nor my sister, or my Mom, I’ve never heard any woman I have ever dated, worked with, or been friends with mention such a thing.
