Review on Men's Razor Blade Sharpener - RazorPit, Black: Enhance Razor Blade Longevity by Jon Odom

I used to use a Mach 3 razor and this item was sharpened to a point where it was better than the factory. I would easily get a month and a half for a medium beard. In fact, the blade's body would fall apart if I used it for any length of time. I lost track of my Pete for about a year and that's when I started using the Gillette Fusion (5 blades). Well, because of the high cost of Fusion blades. Bought another Pete. The sharpener works well but I think it needs a little tweaking to ensure all blades are sharpened equally and more time to sharpen the Fusion blade. I've just been out of an alloy blade for a month. But I find it works best for Mach 3. But it worked fine for me.
