Offset knife hinges provide an unobtrusive way to hinge an inset door. Fitting is as shown above and so long as the mortises are cut accurately before assembly installation should present no particular challenge. Accurately is the keyword here. The whole aesthetic of this kind of hinge is lost if door fit is poor and very little adjustment is possible after installation.
To provide a little adjustment after installation the door mortise can be cut a little short and the hinges installed with a singe screw each. If after the casework leaves are screwed into place and the door is slid onto its leaves it is found the door need adjustment one or both mortises can be lengthened slightly as necessary.
