How to Make Whips

I was only looking at some sewing books - in particular the "Plush-O-Rama"/softie type I've been reading about on the blogs...and I scrolled down to see "Customers who bought this book also bought/you may also like" --- "How to Make Whips" and "The Complete Guide to Sharpening". A rather odd suggestion, at least for me. The whips weren't the kind you drink nor cook with, either. Thanks, but no thanks!
