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.
Golden rule of thumb found below for purchasing suggestions:
Light Shaver (1-2/week): 3 Blade Packs per Year
Every Other Day Shaver (2-4/week): 4 -5 Blade Packs per Year
Everyday Shaver(5-7/week):7 -10 Blade Packs per Year
