This is a handy, inexpensive little reference. I've learned to tie dozens of knots, but a quick reference has proven really handy. The plastic seems durable, the size is right, and I really like the way it folds out into a ruler. The only reason I knocked a star off is because unless you've already learned how to tie some of the knots, the instructions aren't detailed enough. In other words, I wouldn't hand this to someone that's never tied some of the knots and expect them to 34;get it34; without some help. If you know your knots, however, and just need a quick reminder, this is a great product.
