Now, what is the real world? The Y1 keyway is one of the toughest you are likely to encounter in real lock installations in the US. The most comprehensive treatment of raking techniques I've found is in the Finch Manual of Lock Picking, although other authors have different perspectives on the subject. Raking, in contrast, is a class of picking techniques in which several pin stack may be set at the shear line simultaneously. Some lock manufacturers and locksmiths install special "security pins" intended to resist lock picking. The first sign of spool and mushroom pins is that the lock will appear to be picked, but will only turn a few degrees. While pins are usually set by raising the cut from the plug to the shear line, they can also be picked by first oversetting the cut to within the shell and then lowering it to the shear line. The most common security pins are the "spool" and "mushroom" top pin designs, which are thinner in their mid-section.

Picking locks with spool and mushroom pins takes practice, both to recognize them and to effectively neutralize them when they are encountered. Again, try to find and lift all the pins with the different hook picks without applying any torque. Alternatively, you can use the rounded edge of an inverted hook pick instead of a special rake pick. Very "wavy" rake picks can simulate various key profiles, and can be surprisingly successful at opening poorly-made locks. Not all locks use a physical key. Once you've mastered the AR1 keyway locks, repeat exercises 2 through 6 with the "Ilco SX" keyway locks. Over time, accumulate a varied collection of practice locks, and study different lock designs whenever you get the opportunity. The large board has locks with eight different keyways, representing many of the most common keyway designs used in the US. This technique requires a great deal of practice to master, but has the surprising property of sometimes being more effective against better made locks. You'll probably want to use one of the smaller LAB picks, although the small Peterson hook will sometimes do with care and practice. It will take a bit of practice to find just the right technique.

To pick this keyway, you'll need a small hook pick and a bit of twisting as you lift. Pin stacks with partially set spool and mushrooms, on the other hand, will feel a bit different. The pin stacks with regular pins will feel just as you'd expect, with a hard stop when the bottom pin hits the shear line. As the peaks hit the pin stacks, energy is transferred from the bottom pins to the top pins, much like the action of the cue ball in billiards. For a take-off his conclusion is that you can hit much more into the croqueted ball. 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. This keyway is more "open" than the Arrow, and there aren't really any "platforms" on which to pivot your pick. There are locks with two, five, and six pins in each keyway, but the keying codes aren't labeled on them.

Now apply heavy torque, with the aim of pinching all the bottom pins at the shear line. Some people within Google argue that the only people who can afford in-house day care now are top level executives. If you can pick all (or at least most) of the locks on this board, you are well prepared against the typical locks installed in residential and commercial buildings in the US. Master ring cylinders (which are no longer in common commercial production but were once marketed by Corbin) use this mechanism to provide independently-keyed master keying. Many inexpensive locks are grossly misaligned, making them quite forgiving of chaotic picking technique. So far, we've been picking locks "a pin at a time," with a single pin stack set at the shear line in the sequence dictated by whatever misalignments are present in the cylinder. If the shear line is within this gap as torque is applied, it may set.
