some might have seen this knot done in some of my video as well as AK's stringfest video. here is the same knot shot with more clarity and detail. i have been using this knot for over 200 string jobs and it is perfect. AK says we need an extra half-hitch but i have skipped it to keep it compact and never found any slippage. the key part of this knot is how it allows tensioning on the string using a pair of pliers and it locks the tension in. that eliminates any slack on the knot.
