I've also kind of got minions who can find this sort of thing out for me, looking for them all myself would've taken... well, back home I've been looking for them for near a decade, so that's a good example right there.
Though I do find myself curious as to what it says about the society that had them that the last of Sweeney's razors and the Lust/Chastity ones were the only ones that had blades still.
And I, uh, kind of can't ask the proprietor now, oops.
