The coatings on the blade are a greater determinate than sharpness for blade longevity. If the coatings not are as "hard" or durable as another blade's coatings that has the same sharpness, it will dull relatively more quickly.The Feathers go 2 rounds for me. Iridium's went 3 rounds easy but I stop at three.
Ya think the feathers crap out soon because they are so sharp?
Go through your sampler and find the blade(s) you like.
When you have a supply of them, start off with 2 shaves on a blade, and change blades. Make a mental note of how differently it feels.
Keep extending the time by a day until the difference is noticeable, then subtract a day and that is your blade change rotation.
Excellent advice!
Oh and BTW, I just realized this morning that I had my 15th shave on a Gillette 7 O'clock SharpEdge (Yellow). I normally rotate my blade 1x per week.
the Gillette Yellow is one of the better blades that sadly do not get enough good press.Excellent advice!

I tend to go for 3 shaves of 3 passes each before I change a blade. I never actually had a negative shave because the blade has been used too much. The blade that is currently in my R89 is a Tesco Personna and it has already done 2 shaves of 3 passes each, so I think I will see how long I can make it last for.
This morning I had the fourth 3 pass shave with this Tesco Personna and it TBH it wasn't the best. It was a bit snaggy on my ATG pass and I got a couple of nicks on my XTG pass. I also have a little irritation. I am going to say that a 3 shave limit on a blade is a good limit for me.
I'm following this with interest, because I've been documenting my experience with a store brand Personna in another thread. It's not a top-notch blade, but it is good and could serve as a daily blade for some.
