Pressure. Don’t apply much of it, just let the weight of the razor glide over your skin.
Short Strokes. Rather than dragging your razor in one continuous motion, which increases the chances of nicking your skin, shave in short strokes (a few inches at a time), rinsing your razor in between.
As the razor doesn’t have a flexible head, short strokes allow you to catch all the different angles of your body.
Angle. Unlike disposable razors, safety razors don’t have a pivoting head. You have to control the angle of your razor — aim for a 30-35 degree angle.
Proper assembled. If your razor isn’t assembled correctly, it won’t work. Make sure the plain smooth side is against the handle.
Baby steps. Take it slowly while getting used to this new way of shaving.
