A very useful book. It is, as it says, how to tie 200 practical knots. The diagrams are very clear. There is a nice rating system of what the knot is good for, how hard it is to tie and untie. Strangely, that rating system is explained on the copyright page. If you need to know how to tie a Portuguese or Spainish Bowline, this is the book. Didn't know there was a Portuguese or Spainish bowline? Then this is the book for you. ( )
