A ratcheting tool including a handle formed with an integral yoke at a first end and a tool head coupled to the yoke at a pivot. The slurry used is based on ethanol-water and contains metal carbide and metallic raw materials as well as stearic acid and a low concentration of polyethylenimine. The MOSFET has a p-type base layer 4 and a n-type source layer 5 selectively formed on the surface of the p-type base layer 4. The support member is selectively positionable along the length of the slot or in the bores such that the tablet is suspended under the force of gravity in a skewed orientation relative to the support surface. The controller uses a single current sensor for plural windings and preferably a single heat sensor within the controller.
