Your basic set of PLT will consist of one diamond, two lifters, and two tension wrenches, This will allow you to work 90% of the locks you encounter.

Several measurements are necessary to size the PLT to a particular lock, and also to you own opening technique.

Collect keys for your two sample locks and examine the different bitting depths. You are looking for the maximum height difference between two adjacent bitting appreciable height difference, but occasionally just by chance, there will be nothing but slight differences in biting depths.

As you expand beyond a basic PLT set, you may want diamond picks with lower height diamonds

The working end of a lifter is merely an upswept curve with a small flat spot on top to hold the pin. Remember, a diamond is pointed, but a lifter has a flat on the top.
