A knife is a wedge.
A knife edge bearing is used to provide a low friction pivot point for a slow moving, low loaded rocking arm; for example a balance beam as in the old-fashioned shop weighing scales. The rocking arm is supported at its pivot point by a cross bar. The two ends of the cross bar are machined such that a line across their bottom edge becomes a knife edge, with the two faces of the knife blade forming an angle of about 60 deg. This knife edge pivots on two supporting pillars, one each side of the arm, which carry the weight of the arm and any applied loading. Very simple and reliable, the only problem being with wear of the knife blade over time, especially with heavier loads or fast repeated movement.
