You're wrong. that is not a point or heel. That is the tang.
I am restoring a set just like it atm.

Those razors come with 1 set of scales + shank, and you can click the razor into the scales via a spring mechanism. That's why the tang is shaped like that. It's a key/lock mechanism.
The one I am working on is > 100 ys old, but the fit of the spring mechanism is still tight and functioning correctly.

This was done to make the whole set compact, as the box only has to measure 4" by 2,5"
The blades themselves are close to 2,5" instead of 3"

A set in that condition is actually very nice, and worth quite a bit.
EDIT: just to be clear: all 7 razors will look like that. It's how they are supposed to look, and I feel lucky that I have the opportunity to restore that set for JMS, even though I will have to send it back when it is ready.
