Anyone Know a Know that ties really tight?

Question

Does anyone know a knot that is fairly easy to tie and is unlikely to come undone. Must be able to tie two poles/sticks togeather.

Thanks

Answer 1

Scouting has done this for some years, they call it lashing:

There are other knots too:
The scaffold knot:

(use the 2 poles instead on one plank, not as secure as the lashings.)
The transom knot:

(a little down on the page) not easy to get undone.

Do not rely on a reefknot or square knot if there is any change that someone gets hurt or something gets broken when the knot fails.

If you want more help, the International Guild of Knot Tyers have a forum:
