The ordered pictures allow one to construct the knots mostly correct first time. In just one or two cases I felt that the final picture was missing (e.g. the Lighterman's Hitch).
It was interesting to find that since I read the Ashley Book of Knots some thirty-five years ago, new knots have been invented, which Geoffrey Budworth includes in his book, e.g.the Albright Special Bend, the Cow Hitch Variant, Clinging Clara, the Icicle Hitch (a truly amazing knot) and others.
The only criticism I can make is that the background information is, for an Encyclopaedia, rather limited.
I shall certainly explore the other works of this acomplished author.
Though not "Ultimate", I do like this book, especially for the new knots that the Day and Ashley books do not cover.
