I thought I'd write an opposing viewpoint, because - with the greatest respect to Mr. Edmundson - I don't agree with the previous review at all.
Firstly, I'm a complete toy addict; I make a point of visiting fetish shops whenever I'm in a new city, and have seen the best that Paris, New York, Boston, Montreal and Toronto have to offer, and I can honestly say that with the exception of *giant* furniture (like cages and thrones), there just isn't that much out there that this book doesn't cover... from the small but highly useful items (cuffs, blindfolds, collars) right up to a bench and St. Andrew's Cross that are both collapsible/portable and probably the cleverest designs I've seen.
Secondly, I did some page counting: pages 205-238 are devoted to instructions for making some rather nice floggers, and 145-161 to making the Turk's Head knots that go on the end of the more expensive ones, but pages 239-248, 257-280, and 287-396 contain plans on making the bench, the cross, suspension cuffs, manacles, a sling, a vacuum bed, harnesses, canes, gags, cbt toys, and a myriad of other things. Given that the book is 398 pages total, according to my abacus that's 8.2% floggers, 4% Turk's Heads, and 35.4% other projects; and the first third of the book covers all the techniques you might possibly need to build everything (and then some). I've no idea what more Mr. Edmundson was looking for, and suspect that Demonia, LeatherMan, Eros Boutique, Il Bolero, and NorthBound Leather wouldn't know either, but perhaps he just wants help remodelling his kitchen. :-)
Personally, I thought the book was fantastic. As mentioned above, it's encyclopedic, and coming from a toy conoisseur like me, that's saying something. About the only criticism I can think of is that there's SO much stuff in there that, despite a reasonably clear layout, it feels a bit overwhelming. If you have any interest in bondage toys, though, and (like me) covet BDSM gear beyond what your wallet can keep up with, you should definitely try this book.
