How to Tie the Wilson (Pro) Knot
Posted by Rob Marshall on 30th June 2019
Step-by-step instructions for tying the Wilson (Pro) Knot, an alternative to the double half hitch.
There are a variety of knots that can be used to tie off the end of a string. The double half hitch knot is perhaps the most common and is the simplest knot to learn. The Parnell knot and PC knot are also common alternatives, while some experienced stringers may even use a ‘signature’ knot of their own to mark their work. Whichever knot is used, it must secure the tension without damaging the anchor string (the string that is already installed and tensioned) and it must not come undone.
