I found the key is to dry the razor after use. The blades don’t last when put away wet. One blade will last 6 months with a comfortable, smooth shave if put away dry. I use the Gilette Fusion. No batteries.
“I use the Gilette Fusion” Same here. I tried a cheapo razor the other day and noticed a real difference.
I strop the blade every time using a small razor strop to keep it sharp, and a cartridge lasts a long time with no `sticking’ or pulling.
A strop or you could use an old belt or surface of a mirror.
I have Shick razors I use and Gilette Fusion razors I use. I shake both off the same number of times before putting them away, yet the Gilette ALWAYS has the shorter lifespan. And by a lot!
My own opinion is that they (Gilette) do something to make the blades wear quicker.
