The first time I installed knife hinges I did so with an inexpensive pair, thinking it would be a good way to learn the process without wasting a lot of money on what is a notoriously finicky piece of hardware. Instead, I learned why quality knife hinges are worth every cent.
Any play or wiggle in the hinge will show up in the swing of the door, and making adjustments after installation is difficult if not impossible. Knife hinges made of thin, stamped steel, with irregularities in the thickness of the leaves or imperfections in the action of the pivot, simply won’t function as they should. You can’t pay me enough to use cheap ones again.
