a quick stroke. Let the stroke be slow and even, developing speed gradually until a complete mastery of the movement is acquired.
If the razor is in good condition and not in need of honing, fifteen or twenty strokes in each direction will be sufficient. If, however, the razor should require honing, no amount of stropping will put a keen edge on it. It will usually be necessary to strop the razor each time you shave, and with stiff beards more than once may be required.
