But in saying that, I have got myself into a linguistic trap. Your brain will take care of understanding what I’m saying and you don’t need to worry about it. Jesus found that out and they crucified him for saying so. Probably the best book I've found on picking locks is the Gerry Finch Manual of Lock Picking, which unfortunately appears to be out of print as of this writing. That said, the Peterson hook picks are a bit too large to fit comfortably in more tightly warded keyways, especially those found on higher-security locks. You may find one of the smaller LAB hook picks to be easier here than the larger Peterson picks, although you can usually still pick this keyway with the small Peterson hook. The traditional torque tool is made from stiff, flat spring steel, bent at a 90 degree angle to provide a small blade that fits in the keyway and a long handle to which torque is applied. The handle of the torque tool serves as a lever to turn the plug. Tubular cylinders typically have four to eight pin tumblers arranged in a circular pattern around the circumference of the plug.

The typical combination lock design involves a set of (usually three or four) disk tumblers around a spindle connected to the external dial. 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. It is a worthwhile investment for anyone with a serious interest in the subject, and repays careful study. " So how on Earth can one get a verb out of a noun? If you can find a copy for sale, get it. 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. It's aimed at working locksmiths, and has a broad discussion of picking techniques and principles, albeit with less depth than the Finch book.

Lock picking is useful and worth studying for its generality and simplicity. Lock picking is a core skill of the locksmithing trade and is also of value to those evaluating, investigating, and studying security systems. Another tutorial reference is The National Locksmith Guide to Picking and Impressioning by Robert Sieveking. 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. But the MIT Guide does cover most of the basics and is a quick read. Instead, they use flat "wafers," typically extending across the full height of the plug. And of course there is the surest and fastest method of all: the use of the correct key. 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). 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).

Apply light torque while pivoting a long, wavy rake inside the lock, inserting and removing it slightly as you go. Now release torque and start over, taking care to pick all the pin stacks with spool/mushroom pins while leaving at least one regular pin stack unset (this will require a light touch and good sensitivity). Figure 4. Manipulating pins. Around the circumference of the plug is a shell, which is fixed to the door or container. If pushed up, it eventually sets and the plug turns slightly (and the pin stack's state changes to set/not-binding). A correctly keyed wafer is flush with the plug on the top and the bottom and allows rotation. All billiards games require the basic equipment of a table, cue sticks, and balls.
