The face can be a little raw after the first 3-4 straight razor shaves, no matter what you used before. The angle you hold the blade can make a significant different in the shave and regarding face irritation. The angle can be anywhere from almost flat on your face to around 30 degrees. If your razor is dull, it will usually pull or hurt immediately. If your razor is over honed, it usually glides across the face with ease but removes little or no whisker.

Have fun.
