Blades typically last as long as this thread (started way back in 2006)
I shave using Feather blades, I shave my face as well as my head every morning, recently with a Merkur slant bar (I love the slant bar!), how many days should I get out of a blade? I've been pushing six but I am wondering how often other people change there blades? Thanks Ian
This is truly a complex question.. I'll try to give a simple answer and that is once a week unless needed sooner. The variables of blade (manufacturer), razor (design and adjustability), time of year (I find my beard heavier at different times), and a myriad of other variables complicate the answer. I like the simplicity of changing my blade every Saturday or Sunday and avoiding the end-of-blade-life bad shave.
