Probably showing my age but I still like he water knot / grass knot / tape knot…
Takes me back to the days of knotted slings. Nostalgic as this is I still think it’s a cool knot. A good one to know but it does have potential for failure that we need to be aware of.
If an outside strand of the knot snags when under load it can pull the knot open.
Have a look at this great clip from Richard Delaney over at RopeLab.

Solutions? here’s a few I’ve been thinking about:
- use sewn slings (probably most people do nowdays!)
- orient the knot so it is clear of any possible snags
- Walter Siebert recommends two overhand knots EDK style (check Walters other research)
- Double inline tape knot — my proposal below
To tie this you put two overhand knots in one end of the sling then re-thread the other tail through both knots. You end up with a doubled section in-between the two knots. The downside is that it uses a lot of the tape.
