You have found that “perfect” blade to go with your razor. One that gives you that “baby’s butt smooth” shave every time. Well…almost every time.
Is the very first shave with that new blade kind of…harsh? Almost too sharp? But then all the successive shaves are great? A lot of people have this issue with Feather DE blades, but it can happen with any brand, really.
The answer to that problem might be to “cork” the blade.
It is as simple as running the new blade’s edge through the top corner of a bottle cork (like a wine bottle or a champagne bottle), once (and only once) on each side of the blade. Some suggest running the blade up to three times, but start out with just once and add if necessary.
That will remove microscopic burrs that may be adhering to the blade and “dull” the edge just enough to get past that too-sharp point, without effecting the life of the blade too much.
In a pinch you could also use a Styrofoam cup edge if you don’t have a cork lying around.
(Actually some people prefer Styrofoam, believing that cork is too dense and may reduce the over-all life of the blade.)
Give it a try and let me know how it goes for you!
