How many shave can you get for Derby Extra and Red Personna blades?
Lately, I use the Personna blades like twice for 2 or 3 pass. How often I change the blade for each shave? Because my skin get red rash and nicks after I shave. I really like Derby Extra but I feel the blade is little sharp and also I like is Personna which I had no problem but the only things is my neck is always get red rash.
When I shave, I shave down and then shave up and also across my neck which is across the grain.
