Optimal Configuration of Half Hitches

Half hitches can be thrown in the same direction (two successive overhand hitches) or can be thrown in
opposite directions (an overhand hitch followed by an underhand hitch). Half hitches can also be tied on
opposite posts. Tera and Aberg (37 ) developed a nomenclature for describing flat knots. This was
modified by Trimbos (38 ) to describe the configuration of sliding knots (Table 1 ).

TABLE 1 Nomenclature for Describing Sliding Knots (38 )

Symbol Definition Example
S Sliding Throw Single half hitch
Identical throw around Successive overhand loops around the same
= same post post
Nonidentical throw around Overhand loop followed by an underhand
X same post loop on the same post
Post switching between Overhand loop followed by post switching
// throws and an overhand loop
