The gnat knot (or gnat hitch) is a secure hitch, serving the same purpose as the buntline hitch. Structurally, it is a marlinspike hitch around the standing line – but tied differently. Unlike the buntline, the gnat resists jamming and thus is usually easy to untie even after being heavily loaded. It is the youngest and least known knot on this list. The gnat knot was first documented in 2012 by Roo in the Notable Knot Index.
