experience difficulty when picking wafer locks for the first time. Since
they are not attacked with conventional lifting (which is what all of the
exercises here have focused upon up until this point in the chapter) it
may be hard to imagine just where to start with the raking and jiggling
attacks that are necessary.

Progressive wafer locks

I am not aware of any training supply outfit that sells progressively-
assembled wafer lock sets. You will occasionally see a few for sale at a
conference, but most vendors do not produce them in large quantities.
This is due to the fact that just about can create their own such
kit with ease, quite quickly, for almost no cost. Obtain three or four
wafer locks from a hardware store (check in aisles that feature window
locks, hinges, and hardware for sliding glass doors) that prominently
feature a screw on their tail side.
These locks will usually be able to completely slide apart when that

screw is removed. This will expose the wafers and allow you to easily
yank out any that you wish to remove. Use a pair of needle-nose pliers to
pull (or even a flat-head screwdriver to push) the unneeded wafer(s) out
of the plug, then reassemble it. Trust me, you do need to start with a

-wafer lock. Even attempting a two-wafer lock will seem trivial.
(That is not to say that such locks don’t exist in the real world… they
Wafer locks of this variety often cost five dollars or less. You can

create a whole progressive set, if you really want to, for less than the
cost of a set of pick tools.

Tensioning wafer locks

Some people have difficulty adapting to the oddly square keyways on

wafer locks. Since anything inserted into such a lock can inevitably stick
clear through the wafers within the plug, it is possible that the longer
head of a standard tension tool will disturb the process somewhat. Don’t
be afraid to experiment with a flat tensioner or even a wishbone style
tool. If you are still having trouble when just starting out, try applying
tension to the plug by pressing manually on the tail cam (as shown in
Figure 3.39) as opposed to using a tension tool at all. Once you become
comfortable with raking by this method, you can try working with a
proper tensioner instead.

Figure 3.39 Applying tension to a wafer lock by pressing with one’s finger directly upon
the tail cam instead of using a tension tool. This isn’t something you can do in the real world
(since the tail piece is essentially always hidden from easy access), but this technique can help
you become more comfortable with raking and jiggling a wafer lock when you are just starting

Trust me, it will get easier. If you are having a lot of trouble with
wafer locks at first, you’re over thinking it. Relax, vary your angle of
attack and your tension, and it will all fall into place.
