Abstract
A manual hone for the plural cutting surfaces of a rotary electric razor cutter. A flat stone of rounded peripheral contour is mounted in an encircling plastic retainer. The retainer provides shock absorption and prevention of inadvertent passage of any cutting surface over an edge of the stone. A cushion or cushions may be provided within the retainer for absorbing excess finger pressure and additional shock absorption.

A manual hone for a rotary electric razor cutter with plural coplanar cutting surfaces, said hone comprising, in combination,
- a stone of uniform thickness having flat parallel top and bottom surfaces, the surfaces having rounded outlines joined by a peripheral side,
- and a retainer for the stone formed of a resilient cushioning material and comprising separate inner and outer parts, the inner part having a first portion closely fitting the entire peripheral side and extending substantially beyond said outlines in directions perpendicular to said surfaces and a second portion integral with the first portion and extending in a plane normal thereto, the outer part having a third portion extending in a plane normal to the first portion and a fourth portion integral with the third portion, extending in a plane normal thereto and slidingly fitting over said first portion, the stone being supported fittingly between said second and third portions.
