I received a racket with a long looking tie-off knot and was wondering what knot it is. It appears to be the same knot done two or three times on top of each other and not just a single one. Any keen eyes can identify what knot this is and whether it is good as a tie-off knot?
the top 2 are just half hitch knots one over another. the bottom one is hard to see. half-hitch is the most basic of tie-off knots. doubling it just make it more secure. it can also be used to tie on top of a fancier base knot to double secure it.
Not keen on multiple half-hitches, myself - they make a tall knot, but not a fat one, and it's a fat one you want.
this is not a good knots, it just a ordinary knots, not a badminton string knots,you can try next two video. https://www.youtube.com/watch?v=qK4miBu_M8k knots,https://www.youtube.com/watch?v=-WaZjx6nsaE
