Our wave rakes represent years of research and development. Based on various wave rakes which are commercially available, and in combination with initial mathematical modelling and final analysis on several prototypes, we created these impeccably crafted wave rakes.
Like all lock picks from Multipick, they are made of the finest spring steel, in unrivaled high-tech quality in 0.6 mm-thickness. The waves of the rakes have a length of 25.4 mm in order to eliminate the normally required precise insertion depth and to facilitate simultaneous interaction with 7-pins. The wave rakes are equally tapered from the shaft to tip in order to maximize strength and to eliminate stress concentrations that cause lesser picks to snap. The long plow tip lifts pin 1 instead of bumping into it head on. With a good technique, prompt openings are often possible.
Our new wave rake profiles are based on Christina Palmer's original (2019) quint cycloid and quint sinusoidal waves, which were designed by her and a group of PhDs. To achieve this, advanced Mathematica software was used to create an exact tapered wave effect. Christina Palmer is known for her great passion for locksport. She combines her personal experience with the laws of physics, applying both to the development of these two sophisticated profiles.
We would like to thank Ms. Palmer for endowing us with her wave rake and tension wrench designs.
Digression:
Cycloid curves characterise the wave forms as they can be precisely defined and drawn using parametric equations in CAD programs and have characteristics that lead to useful wave rakes. For example, cycloids are the curves created by the spirograph drawing tool, and also represent the curve of the fastest descent under constant gravity. Many cycloid wave forms were tested to determine the optimal parameters. Most commercially available wave rakes have sharp tips and steep slopes that make smooth raking challenging and also damage the pins. Our short cycloid wave rakes with a sine/cosine ratio of 0.25 provide non-slip action, making it ideal for simple basic locks. Our sinusoidal wave rakes with a sine/cosine ratio of 0 offer gentle action, ideal for hard locks. Both wave forms are available in a quad version for large locks and a quint version for small locks.
While the long cycloid wave rakes are recommended for normal use, and the long sinusoidal wave rakes for gentle use. Short cycloid wave rakes are intended for fine raking.
Caution! The aggressive cycloid wave rakes are sharp like a saw and can damage the pins and the entire lock.
