What is the advantage of a two-handed knot over a one-handed one?

[robertutube]

For beginners it is better with two hand, more control, more like "normal" household or shoelace tying. But once you master one handed it is clearly superior. The mainadvantage is that one end of the thread can be attached to a needle in a needle holder but you will never have to use this end of the string as the loose end, never touching the needle...

this is a square knot, correct? Not a surgeon's.

[robertutube]

Yes, it is a square (or reef) knot: one twist at the bottom, one reverse twist at the top. A surgeon's knot would have two twists at the bottom and one reverse twist at the top. Both are used in surgery.

i see two hands doing the tying

[robertutube]

it means that one hand never lets go of the other side of the string, i.e. you could hold that end with a needle in a needle holder and wouldn´t actually need the second hand...

so by definition there are one-handed and two-handed knots, both have their advantages and disadvantages...

good thing he's wearing gloves

you don't need to have the last two digits out there with the middle finger. Just do it with one finger (the middle) and leave the last two digits down so you can watch your tension on your wound

Good video. I'm glad you showed how to tie twice, with the short end starting on opposite sides of the incision each time.
