A pocket knife is a folding knife with a blade that fits inside the handle and that is small enough to fit in a pocket. Blades are typically no larger than 3 to 5 in. (8 to 13 cm) in length. Pocket knives are very versatile tools, and may be used for anything from opening an envelope, to cutting twine, to slicing an apple.

Big Book of Pocket Knives Reviews I purchased this book for my dad as a gift along with another book and this book was by far his favorite. He collects all types of pocket knives but has many Case Knives and this book had a larger section and more information on "Case". This book also had more pictures to compare too. This book is seriously lacking, and incomplete. I can't imagine that the author spent a lot of time putting this together. Received the book today and returning it tomorrow. There are many books out there that are a lot more informative with more detailed complete information than this one I got this book for my son for Christmas and he really enjoys looking at the pictures and sharing it with his grandpa. The title is misleading. There is not a guide to grading knives in the book. However, I love looking at the old catalogs. I have been collecting knives for a while and this is the only resource I know that has so many pictures of the old knives. I would give it 5 Stars, but the title is problematic, so I give it 4 Stars. This book didn't have but a few peices that I was looking for..The illustration was poor which is not Amazon's problem..Wish I could return for a refund;but know that's not possible..Thank you for you're quick shipping of the item..And I will continue to do business w/you..Gordon Stanley Average Rating:

Pocket-Knives: The Collector's Guide to Identifying, Buying, and Enjoying Vintage Pocketknives Reviews Being familiar with the author's work I was not at all disappointed with this book. While it is rather general overall there are many great photos and diagrams along with informative dialogue to go with them. Makes a great conversation piece and displays very nice on your coffee table. Average Rating:

A guide to collecting pocketknives shows collectors how to identify types of pocketknives and includes information on their manufacture, the leading knife makers, and specialized collecting.

Slipjoint knives

Most pocket knives for light duty are slipjoints. This means that the blade does not lock, but, once opened, is held in place by a spring device that allows the blade to fold if a certain amount of pressure is applied.

These knives often have more than one blade, including an assortment of knife blade types (serrated, plain edged, saws) as well as a myriad of other tools such as bottle openers, corkscrews, and scissors. A large tool selection is the signature of the Swiss Army Knife. These knives are produced by Victorinox and Wenger and issued to the army and sold to the public. The German Army knife is large but light, with two blades opening from each side. It has hard plastic grips and aluminum liners. The United States Army knife, made by the Camillus Cutlery Company, used to have carbon steel blades and brass liners (both vulnerable to corrosion), but is now more durable with all-stainless steel construction. It has four blades opening from the same side. The handle, as manufactured, has rough edges, but these can be rounded, yielding an excellent and versatile knife.

Another method of non-locking knife is the friction-folder. These use simple friction between the blade and scales to hold the blade in place once opened.

Some popular styles of blade shapes are:

* Clip — the upper part of the blade is cut away convexly to form a sharp point directly in front of the handle.
* Spear — edge and back curve together to a point. Probably the most common style of general purpose blade found on pocket knives.
* Drop point — similar to spear but not necessarily symmetrical
* Pen — similar to a spear but smaller. Originally intended to sharpen quill pens, but continues to be used because of its suitability to fine or delicate work
* Sheep's foot (so named because of its appearance) — wide with straight edge and no point, common on boats and ships. Intended for heavier tasks such as carving wood
* Wharncliffe — flat cutting edge with back curve, similar to sheep's foot but with longer curve
* Spay or spey — clipped at the back to form a sort of point, but the clip is very short. These were originally for castrating livestock and are used for delicate work.
* Hook - The inside of the hook is sharp and the outside edge dull, so that a rope or animal skin can be cut without cutting the surface that the knife travels along. These blades are used by hunters for gutting animals and by emergency rescue people for cutting seat belts without harming the wearer.

There are many traditional types of folding knives:

A pen knife is a small and often thin knife with one or two pen blades, that does not interfere with the appearance of dress clothes, when carried in a pocket. They were originally intended for making and sharpening quill pens but are versatile and have remained fairly common. Knives with three or four knife blades are also common. A whittler is slightly larger than a pen knife and has three blades. A stockman has a clip, a sheep's foot and a spay blade. They are usually middle-sized. A trapper is large, with a clip and a spay blade. Another traditional styles is the Sodbuster.

Newer multitools have gained popularity in recent years, often competing with multi-bladed knives, but most of these are rather large for carrying in a pocket. The "main blade" is typically a pair of pliers, but there is typically one or more knife blades included (e.g. spear and serrated), often locking.

The credit card knife is a very thin knife that is the shape and size of a credit card. It is designed to be carried in the wallet along with regular credit cards. Some of this shape of knife also contain other small tools, such as tweezers, or toothpicks.
