If only some1 made good 3 hole blades, like the old gillettes. I finially got, by accident, some old 3-hole blades.
They fit perfectly in the old types, you can actually "adjust" the razor, cause the blades provide much more flex, so when you unscrew it a bit, the parts are tight, they don't wobble. And I guess about 50% thicker.
Imagine a 3 holed, sharp, thicker DE blades, brand new...
