Binding knots are used to secure, wrap or grip objects and usually are made with both ends of the same line. The most common knot that binds is probably the knot used to tie your shoes with shoelaces. We have the Better Bow Knot version in this section. When you need to secure the top of an open bag the Constrictor Knot or Miller's Knot is a good choice. Binding Knots are an important class of knots and it is good to know a few.
