KingsRam,

'Short' edge life is not unusal in the early days of straight shaving. At the start so many things have to come togther, 'just so' !

As the others have said, as your experience builds up, you will find that your edges are longer lived.

As edge life depends on so many variables, a hard and fast figure isn't possible to predict

Good luck and good shaving for the future !

Have fun !

Best regards

Russ
