Th s invention relates to'a razor stropp-ing device, its primary object being to Provide an improved stropping device of simple, durable and efiicacious constructioinflwhich also has the advantage that itcannot be 0perated it the blade tobe stropped therein is not secured in the correct position, risk of damage by'incorrect operation being thereby eliminated andthe general convenience of the device greatly enhanced. The improved stropper is particularly advantageous for use with razors in which the blade projects or may project at about a right angle to the handle and be sufiiciently exposed to'pr'oject between a pair of rolls to sharpen the opposite sides of the cutting edge, disinembering of the razor being thus unnecessary when sharpening the blade. 7 v i i w With this object in view, the stropper according to the invention comprises essen tially a casing in which is a slidable-carrier carrying rotatable sharpening rolls which by simple manipulatory to and fro motion imparted to an operating knob as is usual, are adapted to be moved into contact with the blade to be sharpened alternatelyon opposite sides and are also rotated soasto strop same, the-blade being held stationary in the casing so as to project between the i, A

The invention also resides in the construction and combination of parts, hereinafter described with referenceto the accompanying drawings, and more specifically pointed out in the appendedclaims. V I

The apparatus comprises an outer protective casing 1 having a hinged lid 2, and longitudinally slidable Within the casing 1 is a frame or carrier 3 in which are rotatably mounted pairs of stropping rolls 5, 5 and 6, 6. The pairs of rolls are arranged one at each end of the frame, and are intended for fine and coarse stropping respectively. The stropping surfaces are preferably helically 'quence to this invention. idle portion 8, aslndicated in Fig. 2, is aperthe preferred form of stropping device ac-.

effecting a stropping of one side of the blade. Upon reversing the movement of knob 13 the carrier immediately moves to press the o0- adjacent stropping roll against the other side of the blade, the rolls then rotate, and stropping of this side is effected.
