Make no mistake, any time a knot ends with a half hitch, it is being thrown in there as a backup. If it didn't need the backup, then it wouldn't be there. I could point to hundreds of useful knots that do not end with half hitches. I struggled with this issue of logical consistency for years until I figured out how to tie the running bow tight enough to replace the cow hitch. That is all I'm trying to present in this video.
Anyone and their brother can tie half hitches. If you don't know knots, tie lots! Half hitches should not be the basis for good ropework. We are supposed to be professionals. We are supposed to have a repertoire of highly specialized, bomber knots that just work – period. We shouldn’t be adding half-hitch backups to our knots and praying that they hold. It's nothing personal. None of us can say that we invented any of these knots. It is simple logic. If you told me that the zeppelin bend or the running bow required a backup, then I wouldn't be using them either.
All I'm saying is that a bomber knot doesn't need a backup - it just works. To paraphrase Brian Fantana from Anchorman - "100% of the time, it works every time."
