Bought this set based on low price and good reviews. Works fine for poking logs occasionally and cleaning up when stove is cold, but while using the shovel in the fire, the black coating started bubbling, then caught fire.

Ex Output:
Negative


Ex Input:
This is not a new book;perhaps that's why it is so useful.There is no gobblygook, no arcane economic theories with fancy lables.What there are in this book are many examples of - - if the government takes this action to make this or that happen, the unintended consequences have proven to be and will probably be again something quite different, and usually not positive.Sound experiential economics in my view, clearly written; and a tremendous help to understanding what will probably happen if the nation takes on more debt, subsidizes this or that interest, taxes one interest at the expense of another, etc.I liked it; I could read and understand it.

Ex Output:
Positive

This is basically a beginners guide to traveling, camping, and surviving in the woods. Covers a wide variety of topics from cabin building to snowshoeing. My biggest takeaways from the book are to always have an axe and blanket when traveling in the woods. Also, never explore unfamiliar areas without a compass and a means of fire creation.Don't expect a story. This is a manual.

Ex Output:

Positive
