Biscuit joiners rarely come with accessories and extras, unfortunately, but there are a few things to look out for to add value to your purchase. The joiner from Porter-Cable, for example, comes with a hard-sided carrying case to protect your joiner. Few joiners come with a two-inch blade in addition to the standard four-inch blade, but this is an accessory to watch out for. In addition, keep an eye out for which joiners come with manufacturer’s warranties like those found on the Porter-Cable, Lamello, and Gino Development joiners.
