And that‘a why a well used razor feels like it does. And based on the amount of hair on a woman’s legs vs a mans face it could explain why the razor feels so much worse after a woman has used it.

And don't forget the potential cooties infestation.

That’s bad news for Damascus steel razor makers!

Damascus steel been traced to cooties? All along we thought it was only 5th graders.

Sorry, I do not know what cooties are.

Well............Oxford dictionary proclaims, it being North American in origin and use

Dictionary
coot·ie
/ˈko͞odē/
Learn to pronounce
nouninformal•North American
plural noun: cooties

a body louse.
US
a children's term for an imaginary germ or repellent quality transmitted by obnoxious or slovenly people.

Origin
First World War: perhaps from Malay kutu, denoting a parasitic biting insect.

Not a serious condition, coincides with time before children's hormones kick in, often when attraction is masked by remark "ewwww, she [or he] has cooties!".
Just as funny now as ever.

Thanks. Should not have assumed that it was not in the dictionary.

The morning of August the 5th 1977 after my 5 AM morning shave I held a razor burial ceremony I had returned from being stationed in Germany to FT Jackson SC. 3 days before my ETS. Why I couldn't have ended my tour of service in Germany instead of having to fly to FT Jackson is beyond reasoning but anyway there I was standing at the sink in front of a mirror in the Barracks with half a dozen dulling razors carefully arranged picking up one dragging it across the 3 day stubble on my face then disassembling it inspecting each component then one piece at a time tossing them into the trash bin reciting last rites and bits of the funeral dirge to each piece as i did so, when a young soldier noticed what I was doing asked me Sargent what are you doing.
I replied these razors have served me faithfully for most of the last 6 years I've been counting down the days since 1971 until I would never be required to shave every day From this day forward if I shave it will be of my own volition not because of some regulation requiring my face to be shorn to the smoothness of a newborn babies behind, if I ever own another razor it will be one of those throw away one time use things
I guess that was probably my single most memorable shave of my entire life

Part of richness in language. Many terms aren't in the dictionary, but are in a dictionary, as a regional thing.
