Last week, I had my best-ever shave, with a Featherweight no less. The Treet blade had 2 shaves on it already, and this might have contributed. BBS all over, from the base of my neck on up, including under the jawline and the neck/jaw/ear junction, which is usually tough for me to get smooth. Absolutely NO irritation. None. If the 1912 is a better shaver than that, I can't imagine what it would be like to use one.
