The tong shape holds the isomé and the ribbing isomé is straight, so you can quickly pierce the fishhook. It also comes with a cutter, so you can cut the isomé to your desired length. Use tweezers or diverts until you set the isomet to the tongs, and feed the hook without completely touching the isomete. You can freely use it with a variety of feeding needs, such as axis, chunking, sewing stitching, and tassels.
