Hinge Options for Cabinet Mounting - Face Frame vs Surface Mount

We like to educate people about different hardware
for cabinet mounting as we have come across several
different scenarios in retrofit painting/lacquering.

Face frame reveals can be converted to a 105 degree
hidden or euro cup hinge with Blum hardware from
Rockler or Salice. There is also a more expensive
120 degree soft-close motion option from Salice.

All of them work well in hiding an old surface mount
bar or pin hinge which are common in pre 1980-90's
cabinetry.
