Finger joints are a type of joint where two pieces of material that come together with intersecting complementary rectangular cuts. Similar to a dovetail joint, finger joints are usually cut at 90 degree angles, but can also be triangular.
The strength of the joint depends on the gluing surface. Longer joints are stronger:
Strength: Long grain to long grain joints with ample gluing surface.
Aesthetic qualities: Can vary spacing and sizes of fingers to create a design
Weakness: Must be glued, or it will pull apart.
Originated in created wooden boxes or crates
Finger jointed long lumber pieces
Created by cutting kerfs into the wood on a table saw. The blade gauge determines the width and multiple passes can expand the joint width.
