Spline joint

{{About|the woodworking joint|the machine element|Spline (mechanical)}}

A '''spline joint''' can be viewed as an extended biscuit. Two boards have extended, matching grooves lined up and facing each other. The void between is filled with a thin piece of wood, forming a spline joint. This is very similar to tongue and groove. The difference is that the spline essentially forms a tongue, a 'loose tongue', for both grooves. It is often joined with glue.
