From cues to balls, cloth to accessories, this ultimate guide will help you navigate through the world of billiard supplies and choose the best ones for your needs. Play of the game moved indoors to a wooden table with green cloth draped on it to simulate grass, and edges added to keep the balls in play. By considering these factors, you can ensure that every game played in your billiard room is enjoyable and relaxing for both you and your guests. Known as Paille-Maille in French and as Pall-Mall in English, the name of this game means "ball and mallet". Ball and mallet games are mentioned as early as the 13th century in French texts. The modern pin tumbler lock is quite simple, dating back to ancient Egypt but not commercially mass-produced until the middle of the 19th century. The pins toward the back may feel a bit different from the pins in the front.

While applying light to moderate torque, push and pull a gently rounded rake pick from front to back and back to front along the pin stacks. The pick must be strong enough to resist bending or breaking while lifting pins, yet the shaft must be small and thin enough to maneuver freely around the keyway without disturbing other pins. These imperfections are very small -- as little as .0001 inches in some cases -- but they are what allow us to manipulate ("pick") locks open without using the correct key. Tubular locks suffer from the same manufacturing imperfections as other locks and so can be picked with essentially the same techniques. Picking depends on weaknesses in the implementation of locks -- small manufacturing imperfections -- rather than fundamental, abstract design flaws that would be present no matter how carefully made the locks might be. These locks are specially pinned to facilitate a more step-by-step approach. In billiards, you must bounce the cue ball off the other two balls to score points, which are referred to as counts.

Note that these two other balls are already on the table, and remember that white and yellow are the cue balls. Popularly, billiards just use 3 balls: one red ball, white one with spot, and white without spot. Each pin stack is cut in one or more places perpendicular to its length. Sawtooth rakes, such as the Peterson "Ripple" and the Falle-Safe rakes, have 5 or more very acute peaks along the length of the pick's edge. The fourth pick is a "rake" of a long sawtooth design (the "Ripple"). The selection of the torque tool is just as important as that of the pick, but, again, commercial pick kits often fail to include a sufficient range of sizes and designs to allow good control and feel across the range of common locks. Mechanical combination locks are common on inexpensive padlocks, safe locks, and to control access to high security vaults.

In general, the torque tool should be as thick as possible while still fitting in the keyway, and of a width sufficient to provide good control but without interfering with the picking tool's access to the pins. 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. See Figure 1. (In practice, the cuts are produced by stacking pin segments of particular lengths, not by actually cutting the pins; hence the term "pin stack.") With no key in the lock, all the pin stack cuts rest within the plug. Good tools are important, to be sure, but once a few basic tools are available the student of lock picking is usually better off investing in new locks on which to practice rather than in new picking tools.
