It is aimed at locksmith practitioners but has a cogent discussion of principles as well as technique. It's aimed at working locksmiths, and has a broad discussion of picking techniques and principles, albeit with less depth than the Finch book. Mechanical locks (and techniques for defeating them) are inherently interesting to many scientists, engineers, and others, and an understanding of the principles for evaluating and techniques for attacking locks, in addition to being useful in its own right, can provide subtle insight into security more generally. Besides, there are other accessories you should know to enjoy a better pool ball game. The 7ft standard pool tables start at $1299. Foldable pool tables start at $899. When you feel confident visualizing and using picks to maneuver around the pins in the AR1 and SX keyways, you're ready to start actually opening locks. In the locked state the plug is prevented from rotating by a set of movable pin stacks, typically under spring pressure, that protrude from holes in the top of the opening in the shell into corresponding holes drilled into the top of the plug. Rotation of the plug within the shell operates the locking mechanism. Other classes of attack, not discussed here but at least as worthy of study and scrutiny, include lock decoding, which is concerned with producing a working key based only on access to the external interface of the lock, lock bypass, which aims to unlatch the underlying locking mechanism without operating the lock at all, and forced entry, which, as the term suggests, involves the destructive application of force to the lock or its surroundings.

The basic design consists of a rotatable cylinder tube, called the plug, linked to the underlying locking mechanism. Picking depends on weaknesses in the implementation of locks -- small manufacturing imperfections -- rather than fundamental, what is billiards abstract design flaws that would be present no matter how carefully made the locks might be. Picking locks requires skill, practice, and the use of rather unusual (and not widely available) tools. Surreptitious entry (e.g., for espionage or law enforcement surveillance) is likewise often best accomplished by obtaining a key or through the use of specialized decoding or bypass tools designed to quickly and quietly defeat the locks used by the target. The book is an encyclopedic guide to mechanical locks, how to evaluate them, and how to defeat them, aimed primarily at investigators, law enforcement and intelligence operatives. For those unfortunate neo-anti-Luddites who refuse to acknowledge the value of anything not available on the Web, I suggest, at a minimum, reading the MIT Guide to Lockpicking, which, while not perfect, has the virtue of being free (and readily available online). While some of these features can be defeated with conventional picking tools and are covered here, picking high security locks generally requires specialized tools and techniques (often designed for a specific brand or model of lock) and are beyond our scope here.

However, it is worth experimenting with different rakes and raking techniques to find one or two that work well for you. Many of the principles can be applied to other keyed lock types, although sometimes the techniques and tools must be adapted. Continue with the AR1 lock board. From the attacker's perspective, too, lock picking is rarely the most efficient, most economical, fastest, or easiest method of entry. For example, the method it calls "scrubbing" is called "raking" by almost everyone else (it's not something I suggest you spend much time on, at least at first, by the way). And of course there is the surest and fastest method of all: the use of the correct key. Criminals generally prefer either procuring a key or forced entry for speed, certainty, and stealth, notwithstanding whatever property damage or evidence is left behind. Few burglars can afford to risk exposure during the time required to pick even relatively easy locks, and unexplained possession of lock picking tools is often considered prima facia evidence of criminal intent. The pick design it calls a "rake" is called a "hook" by the rest of the world (it's the kind of pick you'll be using most).

Over the years, the locksmithing industry has settled on a number of "standard" pick designs. Lock picking is a core skill of the locksmithing trade and is also of value to those evaluating, investigating, and studying security systems. Although somewhat romanticized by popular media and culture, in reality the significance of lock picking is usually dwarfed by other, more practical threats. The principles and skills of lock picking, once mastered, can be applied against the vast majority of commercial pin tumbler locks, and the basic tools, if somewhat unusual, are quite simple. There are a few common errors that you should try to avoid while aiming. In this document. we focus specifically on the conventional "pin tumbler" lock, which is the most common commercial and residential design used in the United States. The first step toward learning to defeat locks is a thorough understanding of how they work, where their security comes from, and how their design and manufacture introduces potentially exploitable vulnerabilities. A detailed introduction to locks is well beyond the scope of this document; we assume here that you already understand, or have access to, the basic principles. I imagine that most of you here are either in college or college educated.
