Tone RDR10S Precision Gear-less Ratcheting and similar items

"A precision screwdriver with a revolver-type bit exchange function. The ratchet mechanism is a step-less gear-less specification." The RDR10S is unlike anything previously seen in the North American market. There are several features and mechanisms to observe and understand here. The RDR10S is a precision screwdriver that includes the following sizes: Phillips (+): PH00, PH0, PH1 Slotted (-): S1.5, S2.0, S3.0 Torx: T5, T6, T8, T10 It is ratcheting but gear-less. Likely a Renold Sprague clutch design as it is silent and no tooth engagement can be felt. The "revolver" bit magazine contains The first six + and - bits listed. These are in the "magazine" at all times until one of them is selected for use. To select a bit, pull the transparent sheath to the open position and use the thumb wheel selector to choose the bit you want to use and close the sheath. The selected bit will now be captivated in the magnetic bit ready to drive. The Torx bits are not in the revolver magazine. They are held in a clip retention area above the revolver magazine and would need to be manually inserted for use. This is a very novel driver that really needs to be in your hands to appreciate. It would be very useful in a situation where you want to carry a set of precision solid state electronic bits but do not want to lug around a canvas bag or wrap full of precision screwdrivers. It is well made and completely at home in a professional electronics repair setting.
