Abstract
A portable grinder, honer and polishing machine is provided which has a horizontally rotating cylindrical grinding wheel continuously cleaned of swarf and wetted by a porous wiper extending into a liquid reservoir in the grinder housing. A tool rest with a phantom pivot point is pivotally and laterally movable relative to the grinding wheel and carries a tool guide protractor which permits accurate horizontal angular positioning of a tool being sharpened. A scissors blade guide is provided to precisely sharpen scissors and a retaining leg is pivotable into an operative position to hold the grinder stationary on a work surface. A tool stop is provided on the tool rest to ensure linearity of the sharpened edge on an elongated tool.
