I only shave with the same blade 1-3 times depending on brand. If I'm going shave with a blade only once and throw it away then the winner is Feather. If you can afford 27 cents at best per 1 shave with Feather, go for it, IMO its as good as it gets. However on shave #2 and beyond, I think my favorite blades, the Indian Gillette Black is a lot smoother(its also pricier((even in India)). Using the same blade on shave #2, I rather shave with Astra, Shark, Supermax, Rapira, or even a Derby rather than risk weepers with Feather.
You can tell anyone anything, as long as you do so respectfully. BOTC member
