A mortice and tenon joint is probably the most iconic woodworking joint. There are three variations - a blind mortice and tenon, a through mortice and tenon and a wedged mortice and tenon.

Dating back thousands of years, the mortice and tenon joint is one of the oldest ways to join two pieces of wood. It comprises a mortice hole and tenon tongue which fit exactly into one another.

It’s a versatile joint that can be used in many different types of woodworking, from fine furniture to large oak framed buildings.

What is a mortice and tenon?

Most of the strength from a mortice and tenon joint is in the downward motion. It's not a strong in the pulling direction like a dovetail joint is. However, with a wedged mortice and tenon, adding wedges to the joint creates a flare, similar to the dovetail, meaning it becomes impossible to pull it apart again.
