Butt joint

A butt joint is a technique in which two pieces of material are joined by simply placing their ends together without any special shaping. The name 'butt joint' comes from the way the material is joined together. The butt joint is the simplest joint to make since it merely involves cutting the wood to the appropriate length and butting them together. It is also the weakest because unless some form of reinforcement is used (see below) it relies upon glue alone to hold it together. Because the orientation of the wood usually presents only one end to a long grain gluing surface, the resulting joint is inherently weak.
