As a general rule my razors wait 8 days between shaves because I slowly built up my rotation. However, in my early days I only had one and it was magic for several reasons:
1) Nenad pointed it [and some others] out to me (hvala Nenade ) and that was the start of our friendship.
2) I got it from Tony H, another friendship
3) It was honed by X (thanks X ). Dang it, it's like a friendship charm
4) Even though it's not much of a looker, it's still my best shaver, period.
For a while I used it and nothing else, on a daily basis, with no adverse side-effects.
