How do you keep track of blade usage?

I change every Sunday and shave with it 'til Friday. I do not shave on Saturdays. When I change brands or razors I wait 'til Sunday.

I change when I feel tugging and pulling! Sometimes I don't and continue to use it, I usually regret it.

I don't really bother. I change them when I feel that more effort is required to get BBS

Monday --- New blade

A new blade every shave works best for me. They're only 5 cents each. For me, having a surgical sharp edge each shave is worth that small price.
