I realize that knots are my passion and bread and butter for technical rescue work, but like anything worth doing (knife sharpening, fire starting, etc.), are worth doing well. Many knots have very unique characteristics, are better in some types of cordage/rope then others and may have significant pros and cons for use in different applications. I would suggest reading up, either from on-line sources or from one of the standard knots guides/manuals and then practice. That is the only way I know of to become both familiar with knot characteristics and knot tying proficiency.

The selection of the ” best” knot/hitch choices can be just as contentious as selecting the “best” knife, flashlight, multitool, etc.

For example I can think of 7 knots/hitches off the top of my head, to tie a rope to a post and I am sure there are many others:

Clove hitch
Figure 8 reweave
Bowline
Slipknot
Butterfly with half hitches
Several half hitches
Girth Hitch
