The Weck razors were patented in 1909 but they were in production at least until the 1960s and maybe later. The latest Wecks were used mainly in hospitals to prep patients for surgical procedures. I have two of the seven-day sets and about twenty other assorted Wecks. It was one of my first razors and I used them quite a lot. I never used the safety guards, preferring the bare blade. But the shaves were always good and they were easily maintained. It's been several years since I have used one of my Wecks, but I might break one out tomorrow - just for old time's sake.
