I don't know about BIFL but I inherited an uncle's 34. He was an every 2nd day shaver. I asked my cousin and she says it is about 30 years old. Give or take a year. Still looks good. There is too much yip around here about Zamac, Pot Metal, etc. Properly done they will outlast us.I wish a SS 34C was available when I started. I loved that razor but I wanted a BIFL item. Hoping the price point is attractive for newcomers
