Our new wave rakes represent Christina Palmer's years of research and development, including evaluation of the Raimundo Bogota and various commercial wave rakes. She performed mathematical modeling, finite element analysis, and multiple rounds of prototyping. In testing these picks, I found them to be extremely effective. The waves span a full inch to eliminate the need for precise insertion depth and enable simultaneous interaction with 7 pin stacks. The uniform tapering from shaft to tip, maximizes strength and eliminates stress concentrations that can cause picks to snap. With good technique, instant opens are possible. This offering is similar to the SERE(tm) style. We call ours: E&E (Evasion and Escape.) To insure durability, these picks are made from our famous "Government Steel." We use our kinetic tumbling system to gain an ultra smooth finish and excellent pick operation in the keyway. One issue with existing picks of this nature, is the operational length tends to address 5 pins or less locks. One of our advances is to extend the reach so that locks having 7 pins or maybe more, can be manipulated. An additional issue in Europe is the clutch action inherent within many of their locks. If the clutch is not pushed to the rear (normally performed by the key) you will find that you end up picking the plug, but the lock will not open. In this kit, you will receive a standard C4-GSP and a longer C5-GSP, plus a long turning tool so you can depress the clutch as you pick. The picks in this set are of the Cycloid variety, and made from Government Steel. Cycloid wave rakes with a sine/cosine ratio of .25 provide grabby action that is ideal for picking locks.
