I have many types of knives, but this one is my favorite. The handle fits into your hand nicely, not too large or small. It has a very nice balance and feel. This makes a perfect gift as well. It's just so beautifully made. Would buy more from the company in future.

Ex Output:
Good Review

This book was purchased as a supplement to our studies. I felt it wasn't organized very well and the questions were not related very well. It does have some good information, but needs re-organization. We got better responses with another study materials we bought instead. If you know what your studying about before doing this book, it's okay. Just don't rely on the answer sheet in the back. The other sources that we found help quite a bit. Overall it is worth what i paid for it.

Ok. It's a nice book, but you can easily find all of this information online for free. It's just an extension of what the free web sites tell you. So there really isn't much to gain from it. I was thinking it would be more helpful than that. Most likely not, since most people know about common sense tips like drink lots water or get enough sleep. Well, if that's your case, by all means go buy the book. Or download any of the many books out there.
