A method and a hand-held device for dermnaplaning is disclosed that includes a blade assembly which includes a blade, a blade holder and a safety cage. In accordance with an important aspect of the invention, the safety cage limits the amount of penetration of the blade into the facial skin to enable the device to be safely used by non-professionals. The dermaplaning device includes a vibration generator that causes the blade to vibrate at a predetermined frequency. Various embodiments of the hand-held dermaplaning device are disclosed for vibrating the blade.

A power pack for a power tool. The power pack includes an electric motor configured to drive a power tool. The power pack also includes a motor controller with a relay circuit communicating with the electric motor. The relay circuit has a switch that may be connected to a power supply, whereby the power supply powers the electric motor. The power pack also comprises non-transitory computer-readable storage media having computer-executable instructions for monitoring operation of the power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: monitor input data relating to operation of the power pack; determine, based at least in part on the input data, that operation of the power pack deviated from an ideal state; and, based on the determination of deviation, cause the switch to electrically disconnect the electric motor from the power supply.

An improved blade for use with an oscillating power tool is disclosed. A rectangular style blade includes side teeth to eject debris and allow rapid but well controlled blind plunge cuts. The side teeth are preferably asymmetric with a forward orientation to bias debris out and the blade inward. Preferably one or more openings or slots allow for additional debris removal. The side teeth also allow for controlled side cutting.

This disclosure relates to a reciprocating saw blade for preparing fish. The reciprocating saw blade can comprise a blade and a wing. The blade can attach to a reciprocating blade. The blade can comprise a tip, a cutting edge, a spine, and a heel. The cutting edge can have continuous wavy serrations formed through a tooth from a plurality of teeth. The tip can form an inward curve towards the cutting edge. The cutting edge can be at one side of the blade while the spine can be at the opposite side. The spine can form an equidistant parallel line with the cutting edge. The heel can be at the rear end of the cutting edge. The wing can be at the rear end of the blade and can have an orifice and a prong. The orifice can be compatible to a quick-release mechanism of the reciprocating blade.

This disclosure relates to a reciprocating saw blade for filleting and preparing fish. The reciprocating saw blade can comprise a blade and a wing. The blade can be attachable to a reciprocating blade. The blade can comprise a tip, a spine, a cutting edge and a heel. The spine can be at one side of the blade. The spine can have a concave form from the tip up to the middle side edge section of the blade and can form a straight edge from the middle section up to the rear side edge section of the blade. The cutting edge can have a continuous set of serrations formed through a tooth from a plurality of teeth. The cutting edge can comprise a grind that divides the spine and the cutting edge. The grind can taper from the middle section of the blade to the cutting edge.
