I'm looking for hinges used on cabinet doors where the hinge pin is visible on the outside, since the hinge pin is in this position the door can be opened a full 180 degrees. Sometimes (the old kitchen cabinet version) the hinge pin is a minimal support, in other cases there is a 'normal' long hinge pin and it is made decorative.
What are these hinges called and where might I find some small[ish] ones I can use on doors which are only 10mm or so thick?
