Before discussing the tool, let’s learn about biscuit joints first. It’s one of the strongest joints to join two pieces of wood. These joints are usually reliable, so you don’t have to worry about them coming off anytime soon.

Usually, a biscuit joint consists of two parts. A chip of wood is compressed and has an oval shape, pretty much like a football. The wooden chip is the biscuit. Then, you must cut slots based on the two wooden pieces you want to join.

Later on, you will need to fill those slots with glue. They swell up when you place the biscuits into the glued slots. The swelling ends up locking the two wooden pieces and joining them with a strong bond.

The joints almost become invisible if you can cut perfect slots based on the biscuits. So, there will be no worries about a bad appearance on the project you are working on.
