* Susceptible to movement: Comb joints are susceptible to movement, especially in humid or dry climates. This is because the comb teeth are not as secure as the pins in a dowel joint or the wedges in a mortise and tenon joint. As a result, comb joints can become loose over time, leading to a weakened joint.
* Limited joint width: Comb joints are not suitable for use on wide boards, as the comb teeth would be too long and would not interlock properly.
* Difficult to disassemble: Comb joints are difficult to disassemble, making them not ideal for projects that may need to be taken apart in the future.
