Yep, that's what they are for. Saw a guy once and he cut a notch in his razor so he could keep track of the numbers.

Actually, from what I have read in other places, it really has nothing to do with that Sam and Brooke (however, that is exactly what I use them for Biggrin ). Rather they are supposed to mean something in the manufacturing process, though what that is I haven't a clue.

My understanding that the numbers are employed during quality control, at the manufacturing point. It allows for proper calibration and alignment of the tooling ie if a random blade is selected and the grind/edge is off, by looking at the numbers, the folks running the machines know what adjustments to make.

+1 i have never intentionally turned my DE blades over and i have never had any issue. Don't worry about turning them over and just use them. They will shave just fine! Biggrin

Of course, you are correct Celestino. However, my OCD insists that I flip the blade so who am I to argue. 24

I doubt turning will have any "stropping effect" anyway. The geometry just isn't there.

If I keep a blade I just loosen the razor and run some hot water over it so it clean for the next round.
