Ok, guys, it's time to vote for your favorite version of the great designs we all love to use. Let's see which one wins out!
Nothing appeals to me like a mid-century TTO design, whether adjustable or otherwise!
[begin history lesson]
From a safety standpoint, you have to be a total moron to consistently cut yourself when changing a DE blade in a 3 piece razor.
In fact, I am not sure the TTO razor was invented by Gillette for safety, so much as it was an attempt at competing with the Schick Injector, who could claim their razor could be loaded without ever touching the edges of the blade.
Gillette in turn invented the TTO razor, so they too could claim their razor could be loaded without touching the blade.
Since the style of blade container that allows the blade to slide out, and directly onto the razor bed is fairly rare these days, the initial reasoning behind the TTO mechanism has been totally lost.

The blade case that allows the blade to slide out right onto the razor bed is sold in almost every grocery, drug, and dollar store in America, thanks to ASR.
I actually prefer a 2 piece slant, followed by a 2 piece open comb. Neither of which are choices in the poll.
3 piece open combs seem to work best for me. But as always, ymmv .
