Want Hinge that opens with less friction than closes



I would like to understand how a friction hinge can be produced so that the Torque for opening is about 35% less or more than the closing of the hinge. Unaware of any material restrictions aside form 'good fit' of pin in hinge channel.

It is easy to picture an elastomeric bushing on the hinge pin with a splined or geared cross-section and 'slanted' teeth like in a ratchet or a centrifugal clutch, such that the teeth easily bend out of the way for one direction of rotation, but tend to jam in the other direction. Maybe there is some sort of one directional surface finish that someone can comment on? .
