Gentlemen:

I have two double edge razors left in my stock, and both are part of the regular rotation with my straights — every seventh shave goes to the double edge. I shave with the same razor three times and then change the blade.

The razors sit in a converted smoking pipe rack. After each three shaves, the razors are switched around in the rack so that I know which razor is next in line. Also, I try to make my mind remember how many times I have used the same blade. Keep using the mind is what I say.

Regards,
Obie
