Razor blade - Replacement pack of 10

In general, we estimate each blade lasting for about 5 shaves; however, this is highly dependent on the density and thickness of whatever is being shaved, be it a grizzly beard or very fine leg hair.  

With that said, we use the following guidelines:

Low Shaving Frequency (1 or 2X per week):  3 Blade Packs per Year

Medium Shaving Frequency (2 - 4X per week):  4 -5 Blade Packs per Year
