A common door lock mechanism in Europe uses a standardized "European profile" lock module. Around the circumference of the plug is a shell, which is fixed to the door or container. Note the border between the plug and shell, which forms the shear line, and the cuts in each pin stack resting within the plug. In an ideal lock, all of the pin holes in the plug would be in perfect alignment with the corresponding holes in the shell, the centerline of the plug would be exactly parallel to that of the shell, and all of the pins would be exactly the same diameter. 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. When there are multiple field kubb in question, it's generally best to separate them with as much horizontal space as possible. There's more to kubb than immediately meets the eye, though. These locks are specially pinned to facilitate a more step-by-step approach.

The basic algorithm for picking locks is remarkably simple: - Apply a small amount of torque to the plug. The basic recommended pick set for this course includes four picks and four torque tools. 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. The plug can rotate freely only if the key lifts every pin stack's cut to align at the border between the plug and shell. 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. Spring steel or stainless steel, between .020 and .035 inches thick, are typical materials. 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.

Picking locks requires skill, practice, and the use of rather unusual (and not widely available) tools. For example, Mul-T-Lock cylinders use special "telescoping" pins that contain two independently keyed tumblers. Special double-sided jiggle-rake picks are commercially available for such locks. Many manufacturers outfit their picks with elaborate and supposedly "ergonomic" handles, but these often hinder performance as much as they might enhance it. If the torque tool is too thin, it will tend to be "springy" and will absorb much of the fine movement and control needed to successfully pick better quality locks. Chances are the two pins will be reversed -- the formerly springy one will give resistance and the formerly stuck one will be springy. 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. Torque tools may be oriented vertically (with the handle in line with the keyway) or horizontally (with the handle perpendicular to the keyway); different people have different preferences. Other differences between picks, aside from the shape of the tip, are the material, finish, width and thickness of the tang shaft, and the shape and material of the handle.

There is a tradeoff, of course, since a longer handle may be difficult to maneuver around obstacles. This ensures maximum comfort even during longer sessions. Using an inverted pick, raise all the pin stacks to their maximum height. The height (or cut depth) of a key under each pin stack position is called its bitting; the bitting of a key is the "secret" needed to open a lock. A key that is bitted to the wrong depth in even one pin position will not operate the lock. If this pin stack is slowly pushed up with torque applied to the plug, eventually its cut will reach the shear line and the plug will turn a bit more. It is not riveting stuff it has to be conceded, and the observations of all those former teammates and opponents who Littlewood managed to speak to in the 1990s are the only thing that tempts a reader not to skim read in the pursuit of more interesting material than bland descriptions of Astill’s cricket. Snooker is different from billiards and pool because three balls can be used as a striker to hit other balls whereas you can only hit the white cue ball in the former.
