Fingerjoint: A series of interlocking fingers prcisely cut on the ends of two pieces of wood which mesh together with heat-based adhesive. It is stronger than a butt or lap joint, and often contributes to the aesthetics of the piece.
Alternate names include box-pin joint or box joint. The advantage of the fingerjoint is that it does not require nails or screws to create a very strong joint once glued. It can be much stronger than a dovetail joint because of the additional intersections that create additional surfaces for the glue to adhere to.
History of the Fingerjoint
The fingerjoint originated as the primary means of constructing quick but sturdy wooden boxes for bringing fruit and vegetables to market. These days it is used to creates a very traditional look for window and door construction.
