What layout has shift-slashes? I'm using a UK keymap with a 105-key ISO keyboard. Slashes are the keys one in from left/right shift. Shift-\ = | and Shift-/ = ?. Is there some common layout where these are reversed as to which is the shift key?
As you can see, in the US variant, it does not have the shift slashes, so it's 104 keys instead of 105. They're not reversed, it's just that the left shift is full size and the slash is near the Enter. From what I've seen, though, it's not merely a US/UK difference, as some manufacturers will keep the left Shift slash button as a double, just to respect the 105-key standard. To me, and apparently @saiya-jin, this is very annoying.
Before I decided on this keyboard, I shopped around found WASD. They do customizable prebuilt mechanical keyboards. Pretty nice. They also have the ISO layout variant, as well as the ANSI variant. Even nicer. But check out these comparison shots I took from their configurator:
