Since good Tying Cord is expensive does anyone know of a good 'Gripping'
Knot that i can easily 'release' at a later date without having to cut
the cord?

The best knot for that is the reef knot, which you can tie tightly
on a corner and move. Alternatively, use a surgeon's knot, followed
by an extra thumb knot, making the top half into a reef knot. The
securest one is the constrictor knot, but that is a b*gg*r to undo.
I use all of those and more.
