I've not seen one like this before.
I'm guessing it's ladies razor, but I'm not sure.
Anyhow, it cleaned up very well and looks near new. (I have the case too)

It was primarily marketed to men but is a good replacement for the Lady Gillette. It is the Knack.

​

Wow!!

Ok, thanks very much.
I thought about "loaning" it to the War Department,
but I'm having second thoughts now.
After this mornings shave, I'm liking it quite a bit.

Maybe the "War Department" needs one of her own. Never hurts to have a spare!

twist in uk, I think.
does the blue color designate anything?

However some of the U.K. Twists have a flattened handle. More like a pry bar than round. So usually the Knack name is used for the rounder version and the Slim Twist for the flattened handle in the U.S. to help identification.

​

Decent head design but the handle was a bad idea, imo. And of course, it's about the only birth year razor I can ever find.

@gorgo2

What is your birth year?

No. In Europe both the Rounded and Flattened handles were both called Slim Twist.

​

In the U.S. the Rounded razor was called the Knack. It was just that the U.S. had the LH Super Adjustable that kept this less expensive razor at bay for so long.

My birth year razor.

What is "a one hit wonder from the late '70s," Alex?

Looks like that was a good year for baby mastadon tusks.

Wow some great detective work, and thanks for the history.

My Sharona of course.

Hmm... so the knurled metal knob is the TTO. So I am assuming all the mechanics are neck up. Could the plastic handle be removed without harming the works I wonder? I am going to have to find one to play with... this gives me an option for birth year I hadn't considered... And if I could customize it with a fancy replate and custom handle. It has the potential to be a fun project. Or an epic disaster. Seems fun either way honestly.

The late CoonCatBob did that work of taking the heads from Knacks and Twists and placing them on new handles.

I get NOS English Slim Twist from a fellow in Holland.
I start out with this.

and end up with this.

I've also used the Knacks but it's harder to find really nice examples.

OK.

Very cool, a 1000% improvement.

I was not the recipient of this. I wish I was. I also wish I had contracted Bob to do some work for me.
