Shaving Made Easy/Chapter 3
CARE OF THE RAZOR.
Take good care of your razor. Many a fine razor has been spoiled by carelessness and neglect on the part of the user. The life of a razor will depend entirely on the care given it. Never put it away until it has first been wiped thoroughly dry, using a piece of chamois skin for this purpose. Even this will not remove all the moisture, so the blade should be drawn across the strop a few times, or else left exposed to the air for a few moments until the little particles of moisture not removed by the cloth have evaporated. Then you may replace the razor in its case with the expectation of finding it in good condition when you next use it.
Rusting must be prevented, especially upon the edge, which seems to rust more quickly than any other part of the blade. A tiny rust spot on this delicate line, by causing the metal to soften and crumble at that point, will soon end the usefulness of the razor, unless the edge is ground back past the rust spot. In such a case there is always the liability of not getting a good edge.
In wiping the lather off the blade never use a glazed or coarse paper. Tissue paper is the best. Many overlook this point and by drawing the blade straight across a glazed or hard finished paper, turn the edge, and then wonder why the razor has lost its keenness. Draw the blade over the paper obliquely, away from the edge, in the same direction as when stropping it.
