Worked for me,
Verified Purchase(What is this?)
This review is from: Razorsharp Razor Blade Sharpener/ Cleaner (Personal Care)
I use a Gillete Mach 3. When my blade got to that stage where I would throw it away because it began to tug and feel rough I used this item as instructed it my blade was good as new. I usually get about 6 shaves out of the blade, now I get double.
I have read a review from another buyer saying he was told to use a pencil eraser, one that's obviously wider than the blade and it works for him. I believe that his method may be worth trying as this item is a bit costly and is made of rubber. I haven't tried the eraser method as I already purchased this item before reading that review and there is no point upsetting myself if it does work.
