The 1930 Gillette New Foldabrush Shave Kit

I would think that 4 knots could be purchased and carved down to 4 slats.

Interestingly the innards of the blue enamel case is gold colored while the innards of the nickel case is silver colored…

The patents must be expired..... I no NOTHING of the process, but could that brush be 3D printed do y'all think?

Just because it can be done, doesn't mean it should be done.

It would be easier just to harvest the hair from one or two knots than cut rectangles out of existing knots. I played around with this idea back when I first got a fold-a-brush set years ago. The original brush was set in vulcanized rubber and wrapped with stamped brass. The only benefit is faster drying time. In exchange, you give up a comfortable handle.

If someone really wants to make a decent 3D printed travel brush, a better design would be a clam-shell handle, with the knot mounted into a rotating gimbal. Open the handle, flip out the brush, close the handle, and off you go. This was actually a patented design, but I've never seen pictures of an actual brush, and only viewed the patent long ago. I saved a picture of the patent on one of my phones or laptops, but haven't been able to find it again.
