Unlike many of the other joints mentioned biscuit joints are one of the less common woodwork joints. This is mainly because there aren't many places where this type of joint is more useful than another type of joint.

As its name suggests biscuit joints are secured with pieces of timber that are in the shape of a biscuit and these pieces of timber help to prevent movement and add strength.

To construct these joints you need to use a tool called a biscuit joiner which is used to cut the biscuit shaped holes in the wood.

This joint is mainly used to join large timber boards together such as the ones you will find on table tops and it is also aesthetically pleasing if the joint is tight. As mentioned above the biscuit shaped pieces of timber help to stop the large timber boards from moving.
