How often should I change my razorblade?
The general consensus on here is 1 week............
Yeah, I change them every Monday.
I can't get a whole week out of mine... maybe 5 days tops and I use a different one for my head and face.
Sensor Excel w/Sensor 3 blades for the face.
HeadBlade Sport w/Sensor 3 blades for the head.
I use the HeadBlade for the Nogging, and a Mach 3 for the face. I change the HB Blade every 5 days, and the Mach 3 about every 8 or 9.
