Have you looked at bubba rope or voodoo? Neither are knockoffs and both have good reps.I want to add a couple of soft shackles to my gear bag. I don't want some knock-off chinese crap. Who makes good shackles from good 'ol amsteel blue?
If you are a DIY kinda person, you can try making your own, it doesn't look too complicated.
Check out Grogs Knots. Cool website if you like or need to tie knots.
