Which blade did you toss today? After how many uses?

Personna Hospital Use (2).

Astra SP (2)

Polsilver SI (4) - barely made it

Astra sp (12)

Feather. 5 shaves. Probably could have gotten more but would rather not press my luck.

Crystal - 6

Astra SP - 5

Personna Med Prep #4

Si - 2

Derby Extra (3) I only threw it away because I was switching to a Personna Lab, and I don't like letting a used blade sit around and then use it again.

Gillette 7 o'clock Yellow (8)

GEM Blue Carbon (1)

Lord Super Chrome (6)

Polsilver SI after four shaves.

Feather 5 shaves

Gillette 7 O'Clock Black - 5

Shark SC 4

Si - 2

Gillette 7O'Clock Black Indian after 9 shaves of 3 passes each. On the last shave, there was little bit of irritation and the shave itself was not that close. Time to move to another blade !
